前S_2蛋白即pre-S_2蛋白,是乙型肝炎病毒(HBV)前S区基因编码的蛋白质之一。近年来的研究认为pre-S_2蛋白与HBV复制有关。为验证其是非我们采用固相血凝业检测pre-S_2蛋白,同时与多项血清学标志及谷丙转氨酶(ALT)作对比分析。现将结果报告如下: 材料和方法一、标本来源:本院1991年1～6月住院 The pre-S 2 protein, pre-S 2, is one of the proteins encoded by the pre-S region of Hepatitis B virus (HBV). Recent studies suggest that pre-S 2 protein and HBV replication. To verify that they were non-specific, we detected the pre-S 2 protein using solid-phase hemagglutination assay and compared it with a number of serological markers and alanine aminotransferase (ALT). The results are reported as follows: Materials and methods First, specimens Source: Hospital in January to June 1991 hospitalization
