Ampicillin belongs to the penicillin group of β-lactam
antibiotics. It differs from penicillin by the presence of an
amino group. It inhibits bacterial cell-wall synthesis
transpeptidases on the inner surface of bacterial cell
membrane. This broad spectrum antibiotic is effective
against Gram-positive and Gram-negative bacteria.
In cell culture, ampicillin is used as an antibacterial agent
and as a selective agent for transformed bacteria. Many
common vectors carry genes encoding resistance to
ampicillin and are identified by the ability of the host
bacteria to grow in the presence of this antibiotic.
Resistance is mediated by cleavage of β -lactam ring of
ampicillin by β -lactamase.
In cell culture applications ampicillin sodium salt is
generally used at a concentration of 100mg/L for
antibacterial use.
Preparation instructions:
Ampicillin sodium salt is soluble in water (50mg/ml).
Stock solution cannot be autoclaved. It should be
sterilized by filtering through a sterile membrane filter
with a porosity of 0.22 micron or less.

Storage and Shelf Life:
Stability of ampicillin solution is dependent on
temperature and pH. Ampicillin in solution is not very
stable at pH above 7. The optimal pH of the stock solution
should be lower than or at pH 7. In addition, the identity
of the buffer can affect the solution stability.
Store ampicillin powder at 2-8ºC away from bright light.
Stock solution is stable for 3 days at 37°C and for
approximately 2-3 weeks at 2-8°C.
For long term storage, it is recommended to aliquot the
stock solution in sterile containers and store at -20°C.
Shelf life is 36 months.
Use before expiry date given on the product label.
