Peptone Y (BSE-Free) (Casein Peptone)

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.\n\nAppearance: Light tan, homogenous, free flowing powder\n\nSolubility: Clear, light amber, complete\n\npH (2%): 6.5-7.5\n\nAsh: (same/less than)15%\n\nMoisture: (same/less than)5.0%\n\nAmino Nitrogen: (same/more than)4%\n\nTotal Nitrogen: (same/more than)10%\n\nUndigested Proteins: Negative\n\nReducing Sugars: Negative\n\nProteoses: Trace positive to positive\n\nNitrites: Negative\n\nTryptophan: Trace positive to positive\n\nGrowth Supporting Properties:\nAgar Formulation, Broth Formulation: Growth Test\nStandard Plate Count: (same/less than)5000CFU/g\nMolds/Yeasts: <100CFU/g\nColiforms: <10CFU/g\nE. coli: Negative\nSalmonella: Negative/25g\n\nTypical 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%\n\nCertificate of Origin: \nThe 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 degrees C for 1 hour including a minimum of 5 minutes at 105 degrees C or greater and then dried at a minimum of 140 degrees C. The enzyme used in processing is porcine-derived from the USA.
