pVSV-G载体

pVSV-G expresses the G glycoprotein of the vesicular stomatitis virus （VSV-G） under the control of the CMV immediate-early promoter. VSV-G is used in pseudotyping of Moloney Murine Leukenia Virus （MMLV）-based retroviral vectors by mediating viral entry. VSV-G interacts with phospholipid components of the target cell membrane and fosters the fusion of viral and cellular membranes. VSV-G does not require a cell surface receptor and can serve as a surrogate viral envelope protein. pVSV-G Vector includes IVS, a synthetic intron known to enhance the stability of the mRNA, the Col E1 origin of replication and bacterial ampicillin rsistance （Amp^r） gene for propagation and antibiotic selection in bacteria.
