产地:Oxoid 货号:LP0037B 规格:500g名称:PEPTONE BACTERIOLOGICAL(细菌学蛋白胨)L37 Typical analysis (% w/w) 总氮 14.0氨基酸态氮 2.6氯化钠 1.6pH值(2%解决方案) 6.2±0.2Oxoid 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.
