Abstract:
Objective To establish an eukaryotic vector of monkey B virus glycoprotein D gene and analyze the expression of gD gene in human embryonic kidney 293T cells.Method First, the protein of monkey B virus glycoprotein D was obtained by gene synthesis.The gene fragments were digested with Pst I and Not I, and ligated to pEGPF-N3. Then, the recombinant plasmid pEGPF-N3-GD was transfected into 293T cells.The expression of gD protein in the cells was detected by Western blot, and the expression localization was investigated using laser scanning confocal microscopy. Results The recombinant plasmid pEGPF-N3 carrying gD gene was successfully constructed, and normally expressed in the 293T cells.Conclusions Glycoprotein D of monkey B virus is expressed successfully in the 293T cells and the protein is located on the cell surface.It may be useful for the preparation of specific recombinant antigen to the glycoprotein D of monkey B virus on cell surface, and can be also used for preparation of antigen slide for detection of monkey B virus.
