其他信息

胰蛋白酶是一种丝氨酸蛋白水解酶,属白色或微黄色冻干粉制品。它能特异性地水解碱性氨基酸精氨酸及赖氨酸羧基所组成的肽键。酶本身很容易自溶，其作用最佳的PH值为8.0～9.0。胰蛋白酶活性能被胰腺中的天然抑制剂所抑制。钙离子能延迟胰蛋白酶的自溶，并能促进胰蛋白酶原的活性。
本品为经TPCK处理的胰蛋白酶，因此，胰蛋白酶活力更高，糜胰蛋白酶活性被抑制。TPCK-胰蛋白酶能够专一性地切割蛋白分子中精氨酸和赖氨酸位点，是蛋白质肽段分析重要工具酶之一。本品为白色或微黄色冻干粉制品。
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. The Aladdin Sequencing Grade Trypsin has been further purified to remove trace contaminating proteases and autolysis products which could interfere in trypsin digestion experiments, and exhibits a single band on PAGE.
