N/A
Stable
No contamination is very safe for the cells and until now, I never had any issues with this. It is important to store them well and avoid freeze and thaw. Following reconstitution, aliquot and freeze (-20°C) for long-term storage or refrigerate (4°C) for short-term storage. Stock solutions are stable for up to 6 months at -20°C or for up to 2 weeks at 4°C.
Efficient
None, overall the only issues depends on the quality of sample.
Overall is a good product safe and efficient to avoid cell culture contamination.
