FAQ

Q.

What effects could freezing and thawing have on my sera?

A.

We generally discourage multiple freezing and thawing of sera. Sera contain proteins, lipids, and other components that may be differentially separated or precipitated out of solution, depending upon the rate of thawing or freezing. This may adversely affect the performance of the sera. The best storage is in a freezer at -20°C or lower.
