Peptone Y (BSE-Free) (Casein Peptone, enhanced)

Peptone Y is a specially formulated enzymatic digest of casein, similar to Tryptone from gelatin, but used to supply higher growth rates when used in molecular biology media preparations such as YPD Broth & Agar. Appearance: Light tan, homogenous, free flowing powder, Solubility: Clear, light amber, complete, pH (2%): 6.5-7.5, Ash: <15%, Moisture: <5.0%, Amino Nitrogen: >4%, Total Nitrogen: >10%, Undigested Proteins: Negative, Reducing Sugars: Negative, Proteoses: Trace positive to positive, Nitrites: Negative, Tryptophan: Trace positive to positive, Growth Supporting Properties: Agar Formulation, Broth Formulation: Growth Test, Standard Plate Count: <5000CFU/g, Molds/Yeasts: <100CFU/g, Coliforms: <10CFU/g, E. coli: Negative, Salmonella: Negative/25g, Typical Amino Acid Profile: Ala 2.8%, Arg 3.2%, Asp 6.7%, Cys 0.3%, Glu 18%, Gly 1.8%, His 2.4%, Ile 4.7%, Leu 7.7%, Lys 7.0%, Met 2.5%, Phe 4.1%, Pro 9.1%, Ser 5.1%, Thr 3.9%, Trp 1.0%, Tyr 1.3%, Val 6.0%, Certificate of Origin: The raw animal product used in the manufacturing of Peptone Y is derived from casein, a milk product derived from bovine, originating in New Zealand where there have been no reported cases of bovine spongiform encephalopathy (BSE). Peptone Y is processed in Mexico. During processing of the product, a batch is heated to a minimum of 80°C for 1 hour including a minimum of 5 minutes at 105°C or greater and then dried at a minimum of 140°C. The enzyme used in processing is porcine-derived from the USA.
