摘　　要：本文采用高速离心等方法从鼠肝中分别获得溶酶体及微粒体,然后对溶酶体及微粒体β—葡萄糖苷酸酶的性质进行了研究。结果表明,此二种细胞器中该酶的最适PH、Km及分子量基本相同,而热稳定性、pH稳定性及等电点不同。The lysosome and microsome were obtained from rat livers by centrifugation and then the properties of β-glucuronidase from these two sources we(?)e studied in detail. The results show that the same pH optimum, Km and molecular weight are observed in both the lysosomal and the microsomal β-glucuronidase,but there are differences between them in heat stability, pH stability and PI.
