Casamino Acids is a hydrochloric acid hydrolysate of casein. Supplies a completely hydrolyzed protein nitrogen source. It contains a small amount of cystine. Tryptophan and vitamins are destroyed by the acid treatment. The remaining amino acids (in varying amounts) are a source of nutrients for various microorganisms. Amino acids are highly soluble and suitable for use in tissue culture. Salt content is typically 30-40%.
