Peptone is an enzymatic digest of protein used to cultivate non-fastidious organisms, producing low-level growth. Deficient in carbohydrates, cystine and tryptophan.||Source:|Pancreatic digest of gelatin, porcine||Appearance:|Light tan, homogenous, free flowing powder||pH:|7.0±0.5||Amino Nitrogen:|≤6%||Solubility (2%):|Light yellow, clear, complete ||Total Nitrogen:|≥10%||Reducing Sugars:|Negative||Undigested Protein:|Negative||Proteoses:|Negative||Nitrites:|Negative||Tryptophan:|Negative||Ash:|≤10%||Moisture:|≤10%||Typical Amino Acid Profile:|Ala 8.5%, Arg 7.8%, Asp 6.2%, Cys 0.2%, Glu 9.8%, Gly 19.4%, His 0.8%, Ile 1.4%, Leu 2.9%, Lys 3.8%, Met 1.0%, Phe 1.9%, Pro 12.2%, Ser 3.7%, Thr 1.8%, Trp 0.05%, Tyr 0.7%, Val 2.2%||Growth Supporting Properties (Agar/ Broth Formulations):|Satisfactory||Certificate of Origin: |The raw animal products and enzymes, porcine tissue, used in the manufacturing of Peptone is derived from meat materials originating in the USA. During processing of the product, a batch is heated to a minimum of 80°C for at least 1 hour, including a minimum of 5 minutes at a minimum 105°C. The product is dried at a minimum 140°C. Note: Higher temperatures are injurious to the integrity of gelatin peptone.
