Merck, B7446-1000ML, Bovine Calf Serum

General description
Animal serum is commonly used to supplement basal media formulations for the optimal growth of many cell types in vitro.
Bovine Calf Serum (BCS) is collected from calves that are less than 12 months old. The serum contains approximately double the protein of Fetal Bovine Serum (FBS). BCS will promote growth in a variety of mammalian cell lines and is often used as a cost-effective substitute for FBS.
Preparation Note
To effectively preserve the integrity of animal serum, it should be stored frozen and protected from light. Multiple thaw/freeze cycles should be avoided as they will hasten the degradation of serum nutrients and can result in the formation of insoluble precipitates.
For stability and optimal performance, serum should be stored at −20 °C and used prior to the labeled expiration date.
Analysis Note
Endotoxin and hemoglobin tested
