胰蛋白酶(trypsin)是胰腺腺泡细胞分泌的一种肽链内切酶,能激活胰腺分泌的酶原,产生糜蛋白酶(chymotrypsin)、弹力蛋白酶(elastase)和羧肽酶A及B(carboxypeptidase A、B).近年来,国外利用敏感的放射免疫分析法(RIA)对血清胰蛋白酶的生理水平,各种胰腺疾病患者血清胰蛋白酶的含量变化,以及不同胰腺刺激时血清胰蛋白酶的浓度变化进行了研究;结果表明RIA测定血清免疫活性胰蛋白酶(immunoreactive trypsin简称IRT)对胰腺疾患的诊断具有重要意义.胰蛋白酶的理化、生物学特性及其产生和作用1962年Buck等首次报道了部分纯化的人
Trypsin is an endopeptidase secreted by pancreatic acinar cells that activates the proenzyme secreted by the pancreas to produce chymotrypsin, elastases and carboxypeptidase A and carboxypeptidase A In recent years, foreign sensitive radioimmunoassay (RIA) on the physiological level of serum trypsin, various pancreatic diseases, serum trypsin levels, as well as different pancreatic stimulation serum trypsin concentration changes The results showed that the determination of serum immunoreactive trypsin (RIA) by RIA is of great significance for the diagnosis of pancreatic disorders.Physiochemical and biological characteristics of trypsin and its production and role 1962 Buck for the first time reported the first part of the purification people
