Expression of multi-copy and immuno-reactivity of recombinant type-specific epitope of herpes simplex virus type 1 / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To express a multi-copy specific epitope recombinant protein of herpes simplex virus type 1 (HSV-1) with immuno-reactivity.</p><p><b>METHODS</b>Multi-copy genes with a specific epitope of HSV-1-glycoprotein G 112-127 were constructed by DNA recombination and cloned in E. coli JM109 pGEM-5Zf. The positive recombinants were determined by SDS-PAGE and Western blotting.</p><p><b>RESULTS</b>The recombinants with 4, 8, 16 and 32 copies of gG 112-127 were obtained. The 8-copy recombinant was expressed by 17.5%, mainly as inclusion body. And it reacted with antiserum HSV-1, but not with antiserum HSV-2.</p><p><b>CONCLUSION</b>The HSV-1-gG112-127 recombinant could be used to distinguish HSV-1 and HSV-2 in ELISA.</p>
