抗原

Homology analysis suggested that the protein could have the structure and function similar to tegumental protein of schistosome and calcuim-binding protein of F hepatica. The prediction results of construction and function domains indicated that the protein has good potentiality as novel viccine against Schistosomiasis.

软件分析结果提示其可能与血吸虫的膜相关蛋白及肝片吸虫的钙结合蛋白有相似的结构和功能，并利用软件对该蛋白质的结构和功能域进行了预测，表明其具有作为血吸虫候选疫苗抗原的发展潜能。

Pike protein consists of S1 and S2 subunit. S1 is head and S2 is rod-shape part, intermolecular effort can bind each other. S1 can bind with host cell epimembranal acceptor. S2 can fix integral Spike protein on the cellular membrane and mediate cell-fusion with virus and host cell. There are significant antigen determinant of virus in Spike protein, genic heterogenesis can effect viral pathogenicity. SARS-CoV Spike protein, which has 23 pieces larvaceous glycosylation sit, consists of 1256 amino acid. Its N-terminals and C-terminals is corresponding conservative.

蛋白是I型膜糖蛋白，介导病毒与宿主细胞膜上的受体结合并与宿主细胞膜相融合。S蛋白由S1和S2两个亚基组成。S1形成球状部分，S2形成棒状部分，两者之间通过分子间的作用力相互结合。S1能与宿主细胞上的受体结合，S2可把整个S蛋白固定在细胞膜上，并介导病毒包膜与宿主细胞膜融合。S蛋白上有重要的病毒抗原决定簇，S基因的突变会影响病毒的致病性。

We detected the expression of VEGF mRNA by in situ hybridization and Ki 67 protein by immune histochemistry.

原位杂交法检测瘤组织血管内皮生长因子mRNA表达；免疫组化法检测瘤组织中细胞增殖核抗原Ki 67的表达。

Objective: To study the correlation between 1H-MRS, histopathology and PCNA expression.

目的：研究MRS、组织病理学与PCNA抗原表达的相关性。

The results showed that the sera samples got from the pigs immunized with Hog cholera haplized virus using bursin as adjuvant have higher antibody titers than those without using adjuvant according to the criterion established here, which is conform to the previous study. This study lay on foundation for standarding the I-ELISA assay established here.

以此方法建立的间接ELISA方法对收集的约120头份血清样品进行检测，结果显示：使用囊素与疫苗共同免疫猪的血清抗体水平明显高于未加囊素组猪的血清抗体水平，与以往的报道一致，为以CSFV重组蛋白作为抗原建立的间接ELISA方法的标准化奠定基础。

The results from the antigen detection on dog saliva and homogenate of brain tissue all were positive.

取犬唾液和脑组织匀浆液进行抗原检测，结果均呈阳性。
