mammalian cell
4.The mammalian cell expression vectors for Mac 1α subunit (CD11b) fused with blue fluorescent protein (BFP) at the carboxyl terminal or for Mac 1β subunit (CD18) fused with yellow fluorescent protein (YFP) at amino terminal were constructed to create recombinant plasmid of pCD11b BFP or pYFP CD18, respectively.
5.ECL Western blotting results indicated that the target gene could express in the mammalian cell line NIH3T3. Conclusion Recombinant plasmid HSP27/pAAV-MCS had been cloned successfully, which would provide the foundation for investigating the role and the mechanism of HSP27 in the ischemia precondition of kidney.
6.METHODS:The pcDNA3.1(+)/ KGPcd was transfected into mammalian cell COS7 with Lipofectamine 2000.The transcription of pcDNA3.1(+)/ KGPcd was assayed by reverse transcription polymerase chain reaction (RT-PCR). The expression product of pcDNA3.1(+)/ KGPcd was detected by method of indirect immunofluorescent.
7.USA is the leader of biopharmaceutical industry, with 79 biotech drugs produced by genetic engineering, antibody technology or cytotechnology, being approved by FDA (18 products expressed by E. coli , 8 biotech drugs expressed by yeast, and 53 biomedicines produced by mammalian cell culture) , of which, 64 are recombinant therapeutic proteins.
