Description
RNA interference (RNAi), a phenomenon in which double-stranded RNA
suppresses expression of a target protein by stimulating specific degradation of
the target mRNA, provides a powerful genetic tool for selectively silencing
gene expression in many eukaryotes (1–6). In mammalian systems, short
interfering RNAs (siRNAs) are the main effectors of the RNAi process (7,8). The
sequence-specific RNAi effect can be observed by introduction of siRNAs into
cells either via transfection or by endogenous expression of 21–23 base
transcripts (8–10).
In vivo expression of siRNAs can be effectively achieved by generating DNA
vectors containing a U1 RNA polymerase promoter, a template for
transcription of an siRNA and a transcription terminator sequence, then
transfecting these into eukaryotic cells. In cells, RNA polymerase II normally
recognizes the U1 promoter to transcribe small nuclear RNAs. The U1 promoter
has been used successfully to generate siRNAs in mammalian cells (11).
GeneClip™ U1 Hairpin Cloning Systems
In the GeneClip™ U1 Hairpin Cloning Systems, siRNAs are expressed as foldback stem-loop structures that are transcribed from the U1 promoter. The
GeneClip™ U1 Hairpin Cloning Systems include linearized plasmids
(pGeneClip™ Vectors) designed for easy and fast cloning of hairpin target
sequences to allow expression of siRNA target sequences in human cells. The
pGeneClip™ Vectors contain the human U1 promoter, which allows
transcription of the hairpin target sequences and generation of hairpin siRNA
in vivo. The GeneClip™ U1 Hairpin Cloning System—Basic is intended for
transient suppression of the gene of interest. The GeneClip™ U1 Hairpin
Cloning System—hMGFP enables easy determination of transfection efficiency
and allows selection of transfected cells by fluorescence-activated cell sorting
(FACS®; 12–14). The other GeneClip™ U1 Hairpin Cloning Systems offer
antibiotic marker options (neomycin, hygromycin or puromycin) for selecting
stably transfected eukaryotic cells so that experimental results do not depend
on transfection efficiency.
Hairpin Insert
Two DNA oligonucleotides, supplied by the user, are synthesized and annealed
to form a DNA insert that contains the hairpin siRNA target sequence. Upon
annealing, the oligonucleotides form ends that are compatible with the ends of
the linearized pGeneClip™ Vector and facilitate a “sticky end” ligation (Figure
1). All of the pGeneClip™ Vectors contain the Ampr gene, which confers
resistance to ampicillin and allows selection in E. coli.

Screening for Successful Ligation
The GeneClip™ U1 Hairpin Cloning Systems are designed to allow easy
determination of successful ligation. Successful ligation of the annealed
oligonucleotides and the vector results in creation of a second PstI restriction
site in addition to the PstI site already present in the pGeneClip™ Vectors. The
presence of an insert can be confirmed by PstI digestion; clones containing an
insert will produce two bands on an agarose gel.
Features
More Vector Choices: These systems provide vectors containing a variety of
eukaryotic, antibiotic-selectable markers for stable transfection, or hMGFP for
determination of transfection efficiency and selection of transfected cells by
FACS® analysis.
Time Savings: Vectors are supplied predigested to eliminate time-consuming
vector preparation.
Convenience: The system includes T4 DNA Ligase, 2X Rapid Ligation Buffer,
Nuclease-Free Water and Oligo Annealing Buffer in addition to the
pGeneClip™ Vector.
Easier Identification of Desired Clones: A PstI digestion quickly identifies
positive recombinants.

Oligonucleotide Design
3.A. siRNA Hairpin Target Sequence Selection
Choose a 19–23 nucleotide target sequence that starts with a "G" from the
coding sequence of the gene of interest. General guidelines for target sequence
selection are continuously being developed (15,16).
Although the existing rules for siRNA selection serve as a reliable guide, they do
not ensure that each selected siRNA sequence will reduce gene expression, and
the optimal target sequence may have to be determined experimentally (17).
!
As a negative control for RNA interference, use a nonspecific target sequence or
a scrambled sequence.
3.B. GeneClip™ Hairpin Oligonucleotide Design
The GeneClip™ U1 Hairpin Cloning Systems are designed to allow easy and
fast detection of successful hairpin insertion. Two hairpin oligonucleotides
(oligonucleotides A and B, supplied by the user) are annealed to form a
double-stranded DNA fragment for ligation into the pGeneClip™ Vectors.
(Figures 1 and 4).
The hairpin oligonucleotides used in these systems are under 60bp in length.
Since detection of a 60bp insert is difficult using an agarose gel, we have
devised a method to allow detection of inserts by PstI digestion. The
pGeneClip™ Vectors contain a single PstI site. Insertion of the hairpin
oligonucleotides creates a second PstI site, and digestion with PstI will
yield two DNA fragments in the presence of an insert. PstI digestion of
pGeneClip™ Vectors that do not contain insert will result in linearization of
the vector (see Section 4.E).
Note: Two hairpin oligonucleotides must be ordered for each sequence tested.
Standard desalting of the oligonucleotides is required prior to use; gel
purification and 5´ phosphorylation are not required.

Oligonucleotide A
Oligonucleotide A forms the template strand for cellular RNA polymerase II
and should contain the following elements:
• Overhang sequence. This four-nucleotide sequence (TCTC) is
complementary to the overhang of the pGeneClip™ Vectors and completes
the U1 promotor sequence.
• Hairpin sequence. Includes:
Target sequence. See Section 3.A. This sequence, in conjunction with its
reverse complement, forms the double-stranded portion of the cellular
siRNA hairpin.
Loop sequence. This sequence provides flexibility for RNA hairpin
formation within the cell. We have tested two different loop sequences
(CTTCCTGTCA and AAGTTCTCT) in our system and observed
comparable suppression levels with each. Other loop sequences reported in
the literature have not been tested (18).
Target sequence reverse complement. This sequence, in conjunction with the
target sequence, forms the double-stranded portion of the cellular RNA
hairpin.
• Additional CT residues. The additional CT residues are required for the
formation of the second PstI site upon ligation of the insert. These two
nucleotides also form the 3´ overhang required for successful siRNAs.

Notes:
a. The 2X Rapid Ligation Buffer contains ATP, which degrades during
temperature fluctuations. Avoid multiple freeze-thaw cycles and
exposure to frequent temperature changes by making single-use aliquots
of the buffer after the buffer is thawed for the first time. Store the aliquots
at –20°C.
b. Vortex the 2X Rapid Ligation Buffer before each use.
3. Mix the reactions by pipetting. Incubate the reactions at room temperature
for 5 minutes. Alternatively, the reactions can be incubated for 1 hour at
room temperature or overnight at 4°C.
4.C. Transformation of E. coli with pGeneClip™ Vectors Containing Inserts
The ligation of fragments with a hairpin can be inefficient, so it is essential to
use competent cells with a transformation efficiency of ‡1 × 108cfu/µg DNA in
order to obtain a reasonable number of colonies. Transformation efficiency can
be confirmed by performing a control transformation reaction using a known
quantity of supercoiled plasmid DNA, typically 0.1ng, then calculating the
number of colony forming units per microgram of DNA.
We recommend using high-efficiency JM109 Competent Cells (Cat.# L2001).
Other host strains, such as DH5α™, may be used. If you are using competent
cells other than JM109 Competent Cells purchased from Promega, be sure to
follow the appropriate transformation protocol. Select transformants on
LB/ampicillin plates. For best results, do not use plates that are more than
1 month old.
Note: The use of plates containing IPTG and X-gal is not recommended.
Vectors containing insert may produce blue colonies. Therefore, blue/white
screening is not appropriate.
1. Prepare two LB/ampicillin plates for each ligation reaction and control transformation. Equilibrate the plates to room temperature prior to plating cells.
2. Remove the frozen, high-efficiency Competent Cells from –70°C storage
and place in an ice bath until just thawed (about 5 minutes). Mix the cells
by gently flicking the tube.

3. For each ligation reaction and each transformation control, carefully
transfer 50µl of cells into a sterile 1.5ml microcentrifuge tube on ice.
Note: In our experience, using larger (17 × 100mm) polypropylene tubes
(e.g., Falcon Cat.# 2059) increases transformation efficiency. Tubes from
some manufacturers bind DNA, thereby decreasing the colony number,
and should be avoided.
4. Briefly centrifuge the tubes containing the ligation reactions to collect
contents at the bottom of the tube. Add 2µl of each ligation reaction to a
tube prepared in Step 3.
To perform a transformation control, add 0.1ng of supercoiled plasmid
DNA to one of the tubes prepared in Step 3.
Note: The pGeneClip™ Vectors are supplied linearized and are not
appropriate as a transformation control.
5. Gently flick the tubes to mix and place them on ice for 20 minutes.
6. Heat-shock the cells for 45–50 seconds in a water bath at 42°C. Do not shake.
7. Immediately return the tubes to ice for 2 minutes.
8. Add 950µl of room-temperature SOC medium to each tube. LB broth may
be substituted, but the number of colonies may be lower.
9. Incubate the tubes at 37°C with shaking (approximately 150rpm) for
1.5 hours.
10. Plate 50µl of each transformation onto duplicate LB/ampicillin plates. If a
higher number of colonies is desired, pellet the cells by centrifugation at
1,000 × g for 10 minutes, resuspend the cells in 200µl of SOC medium and
plate 50µl of cells on each of 2 plates.
11. Incubate the plates overnight (16–24 hours) at 37°C. In our experience, at
least 100 colonies per plate are routinely seen when using competent cells
that are 1 × 108cfu/µg DNA if 50µl is plated.
Notes:
1. The negative control ligation reaction allows determination of the number
of background colonies resulting from the GeneClip™ Vector alone. A
successful ligation reaction with insert typically yields at least 50 times
more colonies than the negative control ligation reaction. The efficiency of
ligation will depend upon the hairpin oligonucleotide sequence.
2. The transformation efficiency of the competent cells can be determined
using the following equation:

4.D. Purifying Recombinant Plasmid DNA
A standard plasmid miniprep procedure can be used for screening of inserts.
The miniprep process can be both laborious and time-consuming, particularly
when large numbers of minipreps are required. A convenient and reliable
method is the Wizard® Plus SV Minipreps DNA Purification System
(Cat.# A1330).
Plasmid purification protocols that reduce the amount of endotoxin in the
DNA preparation are preferred to minimize the toxic effects of endotoxins on
the cells during transfection.
4.E. Screening for Inserts Using PstI Digestion
The pGeneClip™ Vectors contain a single PstI site. A second PstI site is
created upon insertion of the hairpin oligonucleotides, and digestion with the
restriction enzyme PstI will yield two DNA fragments. PstI digestion of
pGeneClip™ Vectors that do not contain insert will result in linearization of
the vector (see Table 1).

Transfection of pGeneClip™ Vector Constructs in an siRNA
Suppression Assay
Once the annealed hairpin oligonucleotides are ligated to the appropriate
pGeneClip™ Vector, the resulting constructs can be used for transient
expression or for stable transfection. pGeneClip™ Vectors that contain a
selectable marker (pGeneClip™ Neomycin, Hygromycin or Puromycin Vectors)
can be used for stable expression of a pool of cells or individual clones.
Transfection of DNA into human cells may be mediated by cationic lipids,
calcium phosphate, DEAE-Dextran, polybrene-DMSO or electroporation.
5.A. Transient Transfection of the pGeneClip™ Vector Constructs
High transfection efficiency is essential for achieving substantial suppression
levels using a transient transfection approach. Prior to testing the inhibition,
optimize the transfection conditions for maximum efficiency in the system to
be tested (see below). The optimal conditions will vary with cell type,
transfection method used and the amount of DNA. When using the
pGeneClip™ Basic, Puromycin, Hygromycin or Neomycin Vectors,
optimization can be performed using a GFP reporter such as the Monster
Green® Fluorescent Protein phMGFP Vector (Cat.# E6421). The pGeneClip™
hMGFP Vector already contains the GFP reporter. The GFP reporter can also
be used to determine transfection efficiency for the assay. To test the
effectiveness of the pGeneClip™ Vector constructs (screening various
sequences for levels of inhibition), the use of a reporter, such as GFP, is highly
recommended. This control can be performed as a separate transfection to
determine the percentage of the cell population transfected or as a
cotransfection where flow cytometry can be used to sort GFP-positive cells.
The level of target RNA suppression in transfected cells can then be
determined by taking the transfection efficiency into account.
Obtaining maximum suppression requires optimizing specific assay
conditions. We have observed variations in suppression efficiency as a result
of the cell line, cell culture conditions, target sequence and transfection
conditions. Varying the amount of transfection reagent, amount of DNA and
cell density can influence transfection efficiency. Obtaining the highest
transfection efficiency with low toxicity is essential for maximizing the siRNA
interference (suppression) effect in a transient assay. Additionally, maintaining
healthy cell cultures is essential for this application. The key considerations are
discussed more fully below.
Cell Density (Confluence) at Transfection
The recommended cell density for most cell types at transfection is
approximately 30–50%; this level is lower than standard transfection
experiments where cells are plated at 50–70% confluency. The optimal cell
density should be determined for each cell type. Maintaining a dividing cell
culture is essential because effective gene suppression requires proliferating
cells. Continued proliferation and the need to passage cells should be
considered when determining the number of cells to plate.

Cell Proliferation
Successful suppression of gene expression requires actively proliferating and
dividing cells, so maintaining healthy cell cultures is essential for this
application. It is essential to minimize the decrease in cell growth associated
with nonspecific transfection effects and to maintain cell culture under
subconfluent conditions to assure rapid cell division. We recommend using the
CellTiter-Glo® Luminescent Cell Viability Assay (Cat.# G7570) to monitor cell
viability and growth.
Time
The optimal time after transfection for analyzing interference effects must be
determined empirically by testing a range of incubation times. Typically little
inhibition is seen after 24 hours, but the maximal suppression time can vary
from 48 to 96 hours depending on the cells used and the experimental targets
tested.
5.B. Stable Transfection of the pGeneClip™ Puromycin, Hygromycin and
Neomycin Vector Constructs
Note: The pGeneClip™ Basic and hMGFP Vectors are not suitable for stable
transfection.
For stable expression, antibiotic selection must be applied following transfection.
Cell lines vary in the level of resistance to antibiotics, so the level of resistance of
a particular cell line must be tested before attempting stable selection of the cells.
A “kill curve” will determine the minimum concentration of the antibiotic
needed to kill nontransfected cells. The antibiotic concentration for selection will
vary depending on the cell type and the growth rate. In addition, cells that are
confluent are more resistant to antibiotics, so it is important to keep the cells
subconfluent. The typical effective ranges and lengths of time needed for
selection are given in Table 2.

determine the concentration that is toxic to nontransfected cells. The miminum
concentration of antibiotic that kills 100% of the cells should be used in
subsequent experiments.
Once the effective concentration of antibiotic has been determined, transfected
cells can be selected for resistance.

1. Following transfection, seed the cells at a low cell density.
2. Apply antibiotic to the medium at the effective concentration determined
from the kill curve.
3. Prepare a control plate for all selection experiments by treating
nontransfected cells with antibiotic in medium under the experimental
conditions. This control plate will confirm whether the conditions of
antibiotic selection were sufficiently stringent to eliminate cells not
expressing the resistance gene.
4. Change the medium every 2–3 days until drug-resistant clones appear.
5. Once clones (or pools of cells) are selected, grow the cells in media
containing the antibiotic at a reduced antibiotic concentration, typically
25–50% of the level used during selection.
5.C. Quantitating siRNA Target Gene Suppression
Reduction of the targeted gene expression can be measured by 1) monitoring
phenotypic changes of the cell, 2) measuring changes in mRNA levels (e.g.,
using RT-PCR), or 3) detecting changes in protein level by immunocytochemistry or Western blot analysis (19–22). The suppression effect will
vary depending on the target, cell line and experimental conditions.
Controlling for nonspecific effects on other targets is very important. As a
negative control, cells can be transfected with either a nonspecific or scrambled
target sequence. This will show that suppression of gene expression is specific to
the expression of the hairpin siRNA target sequences. When suppression is
determined by Western analysis, positive controls for other genes (e.g., tubulin
or actin) should be included. Additional details can be found in reference 23.
Using the GeneClip™ hMGFP Vector, expression of hMGFP allows
normalization of target gene suppression to transfection efficiency.
Alternatively, the suppressive effects can be analyzed only in transfected cells by
separating those cells by FACS® analysis or by analyzing target gene
suppression at the individual cell level. Peak excitation of hMGFP occurs at
505nm, with a shoulder at 480nm, and peak emission occurs at 515nm. hMGFP
expression can be monitored by fluorescence microscopy using an excitation
filter of 470±20nm (470/40nm) and an emission filter of 515nm (long pass).
The psiCHECK™-1 and -2 Vectors (Cat.# C8011, C8021) can also be used to
measure target gene suppression. These Vectors enable the monitoring of
changes in expression of a target gene fused to a reporter, Renilla luciferase,
gene. In these vectors, the gene of interest is cloned into the multiple cloning
region located downstream of the Renilla translational stop codon. Initiation of
the RNAi process towards a gene of interest results in cleavage and
subsequent degradation of the fusion mRNA. Measurement of decreased
Renilla luciferase activity is a convenient indicator of RNAi effect (24).

by making single-use aliquots of the buffer. Use
a fresh vial of buffer.
Incorrect oligonucleotide sequences.
Oligonucleotide A must have an overhang of
TCTC, and oligonucleotide B must have an
overhang of CGTC. See Figure 4.
Improper dilution of the 2X Rapid Ligation
Buffer. The Rapid Ligation Buffer is provided at
a 2X concentration. Use 5µl in a 10µl reaction.
Ineffective transformation or poor-quality
competent cells. Perform a control transformation with supercoiled plasmid DNA to
ensure that the efficiency of the competent cells
is ‡1 × 108cfu/µg DNA (see Section 4.C). The
pGeneClip™ Vectors are supplied linearized
and are not appropriate as transformation
controls.

Low transfection efficiency. Use a GFP vector,
such as the Monster Green® Fluorescent Protein
phMGFP Vector (Cat.# E6421), to determine
transfection efficiency. If the efficiency is low,
optimize transfection conditions, as described in
Section 5.
Inadequate detection. If reduction of the

specificity. Include controls (e.g., actin or
tubulin) in your analysis (20).
Cell growth or viability affected by specific
target sequence. Transfection of the vector may
affect cell proliferation when compared to
nontransfected cells. We recommend
monitoring cell viability and growth to account
for any changes in cell number during the
suppression assay.

8.C. pGeneClip™ Puromycin Vector Restriction Enzyme Sites
The pGeneClip™ Vectors have overhangs of AGAG and GCAG. The listed locations
of the restriction enzyme sites are in relation to base 1 (the T7 RNA polymerase
transcription initiation site). The following restriction enzyme tables were constructed
using DNASTAR® sequence analysis software. Please note that we have not verified
this information by restriction digestion with each enzyme listed. The location given
specifies the 3´ end of the cut DNA (the base to the left of the cut site). For more
information on the cut sites of these enzymes, or if you identify a discrepancy,
please contact your local Promega Branch or Distributor. In the U.S., contact
Promega Technical Services at 800-356-9526. Vector sequences are also available in
the GenBank® database (GenBank®/EMBL Accession Number AY745747) and on the
Internet at: www.promega.com/vectors/

8.E. pGeneClip™ Neomycin Vector Restriction Enzyme Sites
The pGeneClip™ Vectors have overhangs of AGAG and GCAG. The listed locations
of the restriction enzyme sites are in relation to base 1 (the T7 RNA polymerase
transcription initiation site). The following restriction enzyme tables were
constructed using DNASTAR® sequence analysis software. Please note that we have
not verified this information by restriction digestion with each enzyme listed. The
location given specifies the 3´ end of the cut DNA (the base to the left of the cut
site). For more information on the cut sites of these enzymes, or if you identify a
discrepancy, please contact your local Promega Branch or Distributor. In the U.S.,
contact Promega Technical Services at 800-356-9526. Vector sequences are also
available in the GenBank® database (GenBank®/EMBL Accession Number
AY745746) and on the Internet at: www.promega.com/vectors/
