基本描述

产品名称 蛋白酶K 来源于林伯氏白色念球菌
英文别名 Nitrophenyl)methyl (4R,5S,6S)-6-[(1R)-1-hydroxyethyl]-4-methyl-7-oxo-3,4-diphenoxy-5-phosphonooxy-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylate | (4-nitrophenyl)methyl (4R,5S,6S)-6-[(1R)-1-hydroxyethyl]-4-methyl-7-oxo-3,4-diphenoxy-5-phosphonooxy-1-azabicyc
规格或纯度 EnzymoPure™, ≥20 units/mg dry weight
生化机理 蛋白酶 K 是一种稳定的高活性丝氨酸蛋白酶。晶体和分子结构研究的证据表明,该酶属于枯草蛋白酶家族,具有活性位催化三元组(Asp39-His69-Ser224)。它在 pH 值、缓冲盐、洗涤剂(SDS)和温度等多种环境中都很稳定。在 0.1-0.5% SDS 存在的情况下,蛋白酶 K 仍能保持活性,并能消化 DNA 制剂中的各种蛋白质和核酸酶,而不会影响分离 DNA 的完整性。
产品介绍

Proteinase K (PROK) is a serine protease with broad specificity towards aliphatic, aromatic and other hydrophobic amino acids. PROK has a molecular weight of 27,000 daltons and is Ca2+dependent. It is not inactivated by metal ion chelating agents such as EDTA, sulfhydryl reagents, PCMB, TLCK, or TPCK. It also retains activity in 0.5% SDS. It can be inhibited by PMSF or DFP.Useful for the proteolytic inactivation of nucleases during the isolation of DNA and RNA. Removal endotoxins bound to cationic proteins such as lysozyme and ribonuclease A. Reported useful for the isolation of hepatic, yeast, and mung bean mitochondria Determination of enzyme localization on membranes Treatment of paraffin embedded tissue sections to expose antigen binding sites for antibody labeling. Digestion of proteins from brain tissue samples for prions in Transmissible Spongiform Encephalopathies (TSE) research.
