包膜抗原

方法采用Dot-ELISA测定伤寒沙门菌包膜抗原V、菌体抗原O和鞭毛抗原Hd的特异性抗体，并与肥达氏反应相比较。

Methods A Dot-ELISA method was used to determine the specific antibodies of envelope antigen , O antigen and H d antigen in Salmonella . Then the results were compared with the results of Widal 's reaction .

HIV分离株显示明显的变易，特别在包膜抗原&变易性可能促进中和抗性突变株的出现。

目的研究外周血单个核细胞（PBMC）中乙型肝炎病毒（HBV）包膜抗原基因变异的意义。

Objective To study the significance of mutations of HBV preS and S genes in peripheral blood mononuclear cells ( PBMC ) .

由于诱导中和抗体的抗原表位恰好位于其包膜抗原E2蛋白的高变区1（HVR1），因而容易逃避机体的免疫监视，形成慢性感染，同时造成发展广谱预防性疫苗的困难。

The epitope inducing neutralizing antibody in high variable region 1 ( HVR1 ) is the reason for escape of host immune surveillance , evolution of chronic infection , and also difficulty of producing wide spectrum vaccine .

结论本研究成功克隆人核包膜蛋白自身抗原gp210、p62和LBR基因，并将其在大肠杆菌中成功表达。

Conclusion The human plasmid containing gp210 、 p62 、 LBR is successfully cloned into E coli BL21 、 M15 . The results of ELISA show its good antigenicity and specificity .
