Will improper storage of my tissue culture reagents affect the growth rate of my culture?
Yes. Store animal sera at -5 to -20 degrees C. Store media at 2 to 8 degrees C; use within recommended shelf life period. Store complete media (supplemented) at 2 to 8 degrees C, and for complete medium the recommended shelf life is 2 to 4 weeks. Additionally, minimize exposure of sera and media to light.
