Store Kit at 4-10°C ***DO NOT FREEZE*** ******************* ™ EnSens® MMP-14 Activity Detection Kit (Cat. No. 032014_03_25, 032014_03_96, or 032014_03_384) Fluorescence Based Activity Assay for Microplates Note: Your kit is shipped with an ice pack; if your kit arrives at room temperature, no worries. Kit components are stable at room temperature for several days. Kit Components: EnSens® MMP-14 Activity Detection Substrate (stored in 50mM Tris-Cl pH 7.5, 750mM NaCl, 50mM imidazole, 0.1% TritonTM X-100, 0.02% TweenTM 20), 2µM Far Red Fluorogen (FRF dye), 2µM Pre-activated substrate (EnSens®-PA, substrate positive control), 2µM* 2X Assay Buffer Molecular biology grade water Other Required Components: Active protease** (for quantitative standard curve) Microplate (black plate with round- or flat-bottom wells is appropriate) Plate reader with fluorescence detection capabilities Fluorescence Detection: Excitation/Emission: 635 nm (625-635 nm) / 656 nm (655-665 nm) Depending on your fluorimeter, the gain/sensitivity setting may need to be increased manually, and the bandwidth decreased to 5-10nm. Contact us at [email protected] with questions. Suggested Assay Conditions: 50 uL final volume is recommended for 96-well plates and 20 uL volume for 384-well plates. Volume can be scaled from 10 - 500μL; temperature between 4°C and 37°C; assay time can range from 10 minutes to several hours, depending on concentration and activity of protease in your sample. Example Protocol for 5 μL Sample in 50 μL total volume (25-well and 96-well kits): In microplate well or microfuge tube: Mix 25 μL 2X Assay Buffer 5 μL EnSens® Substrate or EnSens®-PA substrate positive control 5 μL Far Red Fluorogen 10 μL Water Mix thoroughly Incubate at RT or 4°C for 15-60 minutes protected from light Add 5μL of your sample containing protease activity*** Mix thoroughly. Read fluorescence at Ex/Em 625-635 nm/655-665 nm *To ensure accurate reads, always set your fluorimeter gain using the EnSens ®-PA, substrate positive control, while keeping in mind that the EnSens®-PA signal will be very strong relative to the signal in your sample wells. **A standard curve of active protease must be run each time a plate is read in order for the assay to yield quantitative results. ***Always add your sample last, after the 15 minute incubation of Buffer:EnSens:Far Red Fluorogen mix. Adjust sample and water volume as needed. For best results, use a range of sample dilutions and perform all assays in duplicate or triplicate.
