storage of foetal calf serum
Posted 15 August 2012 - 06:48 PM
I heard somewhere that you can store foetal calf serum at 4 degrees celsius for about a week, is this true? Or should it always be frozen right up until use? I am just wondering so I can figure out how small my aliquots need to be.

In my opinion, a week at 4C is no problem. I've actually had NCS and FBS at 4C for up to two weeks or so. But unopened, I only open them once, don't want to risk contamination.
