概述

胰蛋白酶是一种胰腺来源丝氨酸蛋白酶,底物特异性针对带正电荷的赖氨酸、精氨酸侧链。它由 34 kDa 无活性前体酶原 —— 胰蛋白酶原,经酶切去除 N 端 6 个氨基酸先导序列后生成,成熟胰蛋白酶分子量为 23.8 kDa。最适 pH 为 8.0。胰蛋白酶可被有机磷化合物(如二异丙基氟磷酸)以及胰腺天然抑制剂抑制;大豆、利马豆、蛋清也是天然抑制剂来源。胰蛋白酶可切割精氨酸、赖氨酸位点的酰胺键与酯键。
酶切特异性:胰蛋白酶在赖氨酸、精氨酸的 C 端侧切割肽键。如果切割位点羧基侧为脯氨酸,则不发生切割;切割位点两侧存在酸性氨基酸残基时,水解速率会明显下降。
组成:胰蛋白酶原切除末端六肽后激活,生成单链 β- 胰蛋白酶;后续有限自降解可生成其他活性形式,由二硫键连接两条或多条肽链。主流形式为 α- 胰蛋白酶(双链)和 β- 胰蛋白酶(单链),α、β 型在活力、热稳定性上存在差异。
技术备注:本产品为无病毒无支原体胰蛋白酶,经 0.22 μm 滤膜过滤、冻干、伽马辐照处理,并完成病毒与支原体检测。
活力单位说明:1 mg 胰蛋白酶 ≥180 TAME 单位、10350 BAEE 单位、3450 USP/NF 单位。
用途:组织培养。

Trypsin is a pancreatic serine protease with substrate specificity based upon positively charged lysine and arginine side chains. It is derived from a 34 kDa inactive precursor zymogen, trypsinogen, after enzymatic removal of an N-terminal 6-amino acid leader sequence resulting in the 23.8 kDa trypsin molecule. The optimum pH is 8.0. Trypsin is inhibited by organophosphorus compounds such as diisopropylfluorophosphate and natural inhibitors from pancreas. Soybean, lima bean, and egg white are also sources of natural inhibitors. Trypsin cleaves amide and ester bonds of Arg and Lys.
Specificity
Trypsin cleaves peptides on the C-terminal side of lysine and arginine amino acid residues. If a proline residue is on the carboxyl side of the cleavage site, the cleavage will not occur. If an acidic residue is on either side of the cleavage site, the rate of hydrolysis has been shown to be slower.
Composition
Trypsinogen may be activated by removal of a terminal hexapeptide to yield single-chain β-trypsin. Subsequent limited autolysis produces other active forms having two or more peptide chains bound by disulfide bonds. The predominant forms are α-trypsin, having two peptide chains and β-, a single chain. Different activity and thermal stability are shown by α- and β-trypsin.
Technical Notes: This product is virus and mycoplasma free trypsin. It has been filtered through **a** 0.22 micron pore size membrane, lyophilized, subjected to gamma irradiation, and tested for virus and mycoplasma.
Unit Definitions: 1mg trypsin ≥180 TAME units, 10,350 BAEE units, 3,450 USP/NF units.
Uses: For tissue culture work.
