蛋白胨是酪蛋白的胰消化。它可用于在任何地方指定胰腺或胰蛋白酶消化酪蛋白的配方。酪蛋白是牛奶的主要蛋白质是氨基酸态氮的丰富来源。剖面显示整个分子量范围胰腺消化特性峰的广泛蔓延。这是经常提到的水解在已经发表的作品，无论是作为一种代谢或生长研究培养基的成分，或其他用途，其中最重要的是高性能和成分均匀。它具有较高的色氨酸含量，因此，在测试的吲哚反应的媒体。
蛋白胨可以检测`平酸罐头行业'或'硫化物，腐败微生物也被用于无菌试验介质，
它是一个组成部分在发酵过程中使用的媒体产生抗生素，胞外蛋白，干扰素和白喉类毒素。

产品说明：
TRYPTONE           Code: LP0042

Tryptone is a pancreatic digest of casein. It can be used

in any formulation where a pancreatic or tryptic digest

of casein is specified. Casein is the main protein of

milk and is a rich source of amino acid nitrogen. The

profile shows a broad spread of peaks throughout the

molecular weight range characteristic of a pancreatic

digest. This hydrolysate is often mentioned in published

works, either as a constituent of culture media for

metabolic or growth studies, or for other purposes where

high performance and uniformity of composition are of

paramount importance. It has a high tryptophan content

and is therefore used in media for testing the indole

reaction.
Tryptone can detect `flat-sour’ or `sulphide’ spoilage

organisms in the canning industry and is also used in

sterility testing media.
It is a constituent of media used in fermentation

processes to produce antibiotics, extra-cellular protein,

interferon and diphtheria toxoid.
