And whether is it necessary to redefine the geotectonic pattern in southern China? In 1993, the authors discovered firstly the late Paleozoic radiolarian silicalite in the "Shuangqiaoshan Group", which, as we know, is a block within the ophiolitic mélange. In 1996, the authors discovered again the late Paleozoic fossils in the other rocks of "Shuangqiaoshan Group" and "Zhitang Formation" of Lower Sinian Series in the ophiolitic mélange. At the same time, the authors discovered firstly the early Paleozoic chitinozoa fossils.

In this research, B2 gene of HCV was highly expressed as a fusion protein (Trx-B2) by cloning into pThioHisA, and induced specific anti-HCV antibody in higher titer than unmodified B2 protein after immunize mice or rabbit.The results showed antigen Trx-B2 has obvious immunogenicity and induced specific antibody,which might be able to serve as diagnosis HCV. Consequently, this PcAb of rabbit was used to coated Immulon plate, and a method of both antibodys sandwiching antigens was developed to detect 32 HCV positive serum and 32 nomal serum.Results show that ratio of positive are 87.5%and 43.75% respectively.

但缺点是该抗原所诱导的抗体滴度较低，可能是由于其分子量较小，所以本课题将人工合成的HCV复合多表位抗原基因B_2克隆到表达载体pThioHisA中，利用硫氧还蛋白融合方式对该抗原进行修饰，并在大肠杆菌中表达融合蛋白(Trx-B_2)，纯化该蛋白后免疫小鼠及家兔，结果表明用硫氧还蛋白修饰后的融合蛋白免疫小鼠和家兔后，得到的抗体滴度均高于未经修饰过的复合多表位抗原合成肽所诱导的抗体滴度，并从免疫后的兔血清中提取IgG包被酶联板，利用双抗夹心法分别检测了32份HCV阳性血清和32份正常人的血清，结果阳性率分别为87.5%和43.75%，符合率为71.88%。
