本试验利用PCR技术扩增了伪狂犬病病毒(PRV)Kaplan株的糖蛋白G(gG)基因,结果显示,扩增的片段长约为1314 bp。将gG基因克隆到原核表达载体pET-30a中,转入大肠杆菌中并经IPTG诱导表达,通过SDS-PAGE蛋白电泳和Western-Blot免疫印迹分析,证实表达了分子量大小约为54 ku的特异性gG蛋白,并能被特异性抗体所识别。本研究为深入阐明PRV gG基因结构与功能及诊断试剂的研发奠定了基础。

The glycoprotein G (gG) gene of pseudorabies virus Kaplan strain was amplified by PCR followed by sequence analysis. The results revealed that the gene fragment was 1314 base pairs (bp) in length. The full-length gG gene was cloned into the prokaryotic expression vector pET-30a(+) , and expressed in E.coli induced by IPTG. The molecular weight of the gG protein was approximately 54ku identified by SDS-PAGE and Western-Blot.The results are helpful for investigat-ing the structure and function of gG protein and preparation of diagnostic reagents for pseudora-bies.
