title: [Cloning of human lysosomal acid beta-glucosidase gene and its expression in COS7 cells].
abstract: In this study, we amplified human lysosomal acid beta-glucosidase (GlcCerase) gene by RT-PCR from human placenta, and analyzed the sequence of the PCR product cloned in pMD-19T. The gene identity was 99% comparable to that of the reported human GlcCerase cDNA sequence in GenBank. The GlcCerase gene digested with Xho I was subcloned into eukaryotic express vector pEGFP-C1 to generate recombinant expression vector pEGFP-GlcCerase. After identified the recombinant plasmid by restriction enzyme digestion, we transfected pEGFP-GlcCerase into COS7 cells by liposome. GlcCerase mRNA was expressed and the activity of GlcCerase was also detected in COS7 cells. This study would lay a foundation for the function of GlcCerase and its production by transgenic bioreactor.
