ABSTRACT
<p><b>OBJECTIVE</b>To clone the glycoprotein G gene and its specific fragment with high conservation and antigenicity by culturing and amplifying herpes simplex virus type 2 and extracting its whole genome.</p><p><b>METHODS</b>We obtained a great deal of suspension with HSV-2 virus after infecting the cultured Hela cells with HSV-2 virus, extracted the whole genome of the virus by the phenol-chloroform method, and amplified the US4 gene coding gG-2 by PCR. Then we selected the specific target fragment according to the amino acid sequence alignment of the gG-2 gene and cloned it with the designed primers with restricted endonuclease sites.</p><p><b>RESULTS</b>We successfully obtained a lot of suspension with HSV-2 virus, and cloned the gG-2 gene from the whole genuine and its specific target fragment. Sequencing showed that both the sequences were identical with those printed in the GenBank.</p><p><b>CONCLUSION</b>It is feasible to obtain the virus genome and specific fragment of the gG-2 gene from virus-infected cells, especially for HSV-2 virus with relatively stable hereditary trait. It has prepared the ground for further constructing the expression plasmid of the specific fragment, expressing related proteins and identifying their antigenicity.</p>
