Abstract:
Objective:To obtain the high expression of Herpes Simplex Virus Type 1(HSV-1)Glycoprotein D gene. Methods:The Herpes Simplex Virus Type 1(HSV-1)Glycoprotein D(gD1) gene fragment containing dominant antigen epitopes confirmed by computer analysis was cloned by PCR technical and inserted into plasmid vector pTrxA. Then the recombinant plasmid was transformed into Rosetta. The expressed product was analyze by SDS-PAGE. Results:930 bp gene fragment was amplified by PCR as anticipated. Nucleotide sequencing showed a 100 % homology with that of the published sequence in GenBank. The molecular weight of the expressed protein was about 48kDa, Western blotting indicated that the antigenicity of the protein was good. Conclusion:The plasmid pTrxA-gd1 was constructed and a high efficiency expression of the gd1 gene from Herpes Simplex Virus Type 1(HSV-1)strain was made. The expressed product shows a good antigenicity.
