胃蛋白酶原(pepsinogen,PG)是胃液中胃蛋白酶的无活性前体,人胃蛋白酶原可分为两种生化和免疫活性特征不同的胃蛋白酶原亚群:按胃蛋白酶原在琼脂凝胶电泳下的迁移率由快至慢分pg 1-pg7七种同工酶,其中pg 1-pg 5 Pepsinogen (PG) is an inactive precursor of pepsin in gastric juice. Human pepsinogen can be divided into two subgroups of pepsinogens with different biochemical and immunocompetent features: by pepsinogen on agarose gel electrophoresis Under the migration rate from fast to slow pg 1-pg7 seven isozymes, of which pg 1-pg 5
