产地：Oxoid 货号：LP0034B 规格：500g名称：PEPTONE BACTERIOLOGICAL NEUTRA（中性细菌学蛋白胨） LP0034 Typical analysis (% w/w) Total Nitrogen 13.9 Amino Nitrogen 2.4 Sodium chloride 3.2 pH (2% solution) 7.0 ± 0.2 Oxoid Peptone Bacteriological and its neutralised form are very nutritious all-purpose peptones prepared by the enzymatic digestion of selected animal protein sources. They are specially prepared to provide a solid foundation in culture media formulations and are compatible with other refined culture media ingredients. The combination of pancreatin and papain enzyme systems ensures that these bacteriological peptones contain a wide spectrum of polypeptides, reflected in their broad molecular profiles.The neutralised form evolved from the original to meet those occasions when a slightly higher pH is required. Both when reconstituted give a solution free of haze, cloudiness or precipitation.
