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.对于胰蛋白酶消化肽，胰蛋白酶:肽的使用比例约为1:100至1:20。本品的典型用途是使贴壁细胞从培养表面脱落。 使细胞解离所需的胰蛋白酶浓度主要取决于细胞类型和培养物代数。 Trypsins也被用于细胞培养过程中的细胞再悬浮，在蛋白质组学研究中用于蛋白质的消化，以及在各种凝胶消化中。 其他的应用包括通过基于膜的技术评估结晶，以及在一项研究中确定蛋白质折叠速率和产量可以被动力学陷阱的存在所限制。
