ABSTRACT
Objective To express human cytotoxic T lymphocyte associated antigen-4 (CTLA4) extracelluar domain in Bacmid-baculovirus expression system. Methods The cDNA of human CTLA4 extracelluar domain was isolated from plasmid pUC19-CTLA4Ig by PCR.The specific cDNA was subcloned into plasmid pFastBacl. The insertion was confirmed by DNA sequencing, and then transposed into Hz8 Bacmid in DH10B. The recombinant Bacmid was used to transform Hz insect cells. The supernatant and cellular lysate were analyzed by using SDS-PAGE. Results A specific protein in the cellular lysate of Hz insect cells containing human CTLA4 extracelluar domain with MW38 x 103 was found. Conclusion Human CTLA4 extracellular domain is expressed in the Bacmid-baculovirus expression system.
