摘要
本文报道用HCVNS5区两段抗原性较好的合成肽研制的ELISA试剂盒及UBIHCVNS5区抗体检测ELISA试剂盒观察14例HCV感染者NS5区抗体的动态变化,证实NS5区抗体如同NS4区抗体一样比C及NS3区抗体出现晚。NS5区抗体总体检出率近似于NS4区抗体;1.55%的血清为单独NS5区抗体阳性;存在NS5区抗体与其他区抗体滴度有互补作用的标本等提示NS5区抗体仍有一定的诊断价值。采用UBINS5区抗体检测试剂盒发现,95.65%(22/23)UBI试剂盒诊断为NS5区抗体阳性的标本中含HCVRNA,6/14HCv感染者用UBI试剂盒检出的抗体出现在ALT再次异常升高或剧烈升高(高于参考值的3倍以上)前后,4/14的感染者抗体出现于ALT首次升高前后(其余4/14的感染者未检出抗NS5抗体),因此UBI抗HCVNS5抗体诊断试剂盒检测的抗体似与疾病的活动有关。
The dynamics of antibody to HCV NS 5 was observed with ELISA coated with 2
different peptides and UBIanti-HCV NS5 antibody diagnostic kit ,respectively. It confirmed that
anti-HCV NS5 antibody appeared later thanthe antibodies to HCV core and NS3 region. 1. 55%of
sera were found to contain antibodies only to NS5 region. The efficiency of ELISA for HCV
antibodies could be improved by adding NS5 antigen as coated antigen. It alsosuggests that
antibody detected with UBI HCV NS5 antibody diagnostic kit may have a good correlation with
theactivity of hepatitis,
