胰蛋白酶选择性水解变性蛋白质中由赖氨酸或精氨酸的羧基所构成的肽链，是一种重要的消化酶。此外，胰蛋白酶还广泛应用于脓胸、血胸、外科炎症、溃疡、创伤性损伤等所产生的局部水肿、血肿及脓肿等的辅助治疗。 测定原理：胰蛋白酶催化水解TAME的酯键，释放出的游离羧基与反应体系中的氢氧化钠发生中和反应，导致溶液的pH值降低，以苯酚红为指示剂，测定溶液在555nm处吸收值的变化，可以快速测得胰蛋白酶活性数据。胰蛋白酶在一定范围内与555nm处吸收值的降低呈良好的线性关系。
Trypsin selectively hydrolyzes peptide bonds formed by the carboxyl groups of lysine or arginine in denatured proteins, making it a crucial digestive enzyme. In addition, trypsin is widely used as an adjunctive treatment for conditions such as pyothorax, hemothorax, surgical inflammation, ulcers, and traumatic injuries, particularly in addressing localized edema, hematomas, and abscesses. Assay Principle: Trypsin catalyzes the hydrolysis of the ester bond in TAME (Nα-benzoyl-L-arginine methyl ester), releasing a free carboxyl group. This group neutralizes sodium hydroxide in the reaction system, causing a decrease in the solution's pH. Using phenol red as an indicator, the change in absorbance at 555 nm is measured, allowing for the rapid determination of trypsin activity. Within a certain range, trypsin activity exhibits a good linear relationship with the decrease in absorbance at 555 nm.
