HBV genotypes were determined by RFLP based on S-gene PCR products.
用S基因聚合酶链反应-限制性片段长度多态性确定HBV基因型。

Objective To construct the clone vector of Sgene in occult hepatitis B virus infection. To analyse its mutations and to construct its prokaryotic expression vector.
目的构建克隆载体，分析隐匿性乙型肝炎病毒S基因的突变情况，构建其原核融合蛋白表达载体。

Conclusions Truncated middle Sgene is found in the circulation of patients with chronical HBV infection, suggestive of a poor prognosis.
