Growth monitored on a plate at 30-35ºC for 48 hrs. Mycoplasma content: Negative by E.I.A. Qualitative Viral Agents (9 CFR 113): None Detected. SOLUBILITY: 50 mg/ml in water, with 15 min of manual stirring. APPLICATIONS/ADVANTAGES: • Designed for a variety of bacterial and mammalian cell culture applications. • Used as a protein supplement in serum-free media for tissue culture. • Promotes and sustains cell growth without toxic effects. • Goes into solution rapidly to form a clear and easily filterable solution.
BioVision’s BSA is prepared by utilizing the Cohn Cold Ethanol Precipitation Process. This process is optimal for preserving the nutrient factors critical to the applications of cell culture, leptospira and microbiological growth. BSA makes up approximately 60% of all proteins in animal serum. It is commonly used in cell culture protocols, particularly when protein supplementation is necessary and the other components of serum are unwanted. It aids in stabilization of enzymes and other proteins to prevent proteolysis and denaturation, especially when the proteins are present in low concentrations. In cell culture its main role is as a carrier of small molecules. Because of its negative charge, BSA binds water, salts, fatty acids, vitamins and hormones, then carries these bound components between tissues and cells. The binding capacity also makes BSA an effective scavenger for removing toxic substances, including pyrogens, from the medium.
