[ACVM] To heat inactivate or not heat inactivate ... that's the question

That was always the rationale I understood as well.

I believe the heat inactivation is to inactivate the complement in the fetal bovine serum so that your assays (virus isolation, virus neutralization and etc) will not be affected.

We done this since the beginning of time (1971 at least) but probably because we have always done it.  I have to believe that Heat Inactivation did some good although what I am not too sure. Regardless, I am reluctant to change this part of the SOP now in case there ARE differences between them and these are reflected in viral titrations, etc etc etc, Steve Krakowka) ________________________________________

To all of you cell culturists out there, I wonder if you still heat inactivate your fetal bovine serum prior to use in cell cultures and other assays. And if you heat inactivate, is it because it has been in your SOP forever or because you actually believe heat inactivation is beneficial?
