| 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 80C for 1 hour including a minimum of 5 minutes at 105C or greater and then dried at a minimum of 140C. The enzyme used in processing is porcine-derived from the USA. |
