ABSTRACT
HIV-1 envelope glycoprotein gp41,which is a hopeful target for HIV-1 fusion inhibitors,plays a critical role in the fusion of viral and cellular membranes.In order to build up the screening assay of HIV-1 fusion inhibitors targeting gp41,HIV-1 gp41 5-helix and 6-helix were expressed in prokaryotic cells.Gp41 5-helix and 6-helix recombined plasmids were constructed by using PCR,enzyme digestion and ligation taking the clade B HIV-1 genome as a template.The plasmid was transferred into E.coli BL21(DE3)and then induced by IPTG.The expressed protein was purified by affinity chromatography after denaturation and renaturation.The SDS-PAGE analysis was used during expression and purification.Native-PAGE was used to identify the interaction between gp41 5-helix and T-20.The result will be helpful to build up the screening assay of HIV-1 fusion inhibitors targeting gp41.
