Gentamycin is resistent to cell culture temperature and pH. In contrast, penicillin and streptomycin are rapidly degraded. Adapted from Schafer et al., J. Appl. Microbiol., 1972.

Traditional antibiotics such as Penicillin / Streptomycin are not the best choice for routine cell culture, due to their instability.

In contrast we recommend the use of Gentamycin, due to the following advantages:

• Broader effective spectrum

• Higher thermo-stability at 37°C (5 days compared to 3 days)

• Longer shelf-life

• Higher acid / alkali resistance (> 90% activity for 2 weeks)

Our Gentamycin/Amphotericin product provides broad and stable resistence against contamination. It is provided in convenient, ready to use aliquots.

The use of antibiotics is only recommended during isolation and passage 1. They may disrupt cell bahaviour and are not recommended for use in subsequent passages, or in particular during challenging processes such as differentiation.
