The results of immunoblot nalaysis nd aELISA assay indicated he tgood antigenicity of he tproteins.The ELISA titers of ntaibodies induced by hese tproteins were 1:32000.Conclusion The P domain and its variant of monkey GII.1 7 norovirus genome were successfully expressed.The antibodies were obtained after immunization ofmice wih tthese two proteins.The ifndings ofthis study pave the way for the development of viral detection kit,viral identiication and assay of virus—receptor binding.f 【Key words】Monkey;Norovirus genome;P domain;Protein expression;Antigenicity 木水水:l=:l=木木水:l::l::l:木木木木木:l::l::l::l:术木水术术木术木木木木木术术:I::I::I=术术木:l:木术术术术:l::l=术术:l=木木:l:木术术:I: 木术:l=:l=木水:l:水木木木木木术:l=木:I:水半术 热烈祝贺上海两位专家荣获2 0 1 6年中国实验动物学 会终 身贡献奖 2016年1O月8~12日,第十二届中国实验动物科学年会在广西南宁国际会展中心隆重召开。会议由 中国实验动物学会主办,广西中医药大学协办,广西实验动物学会承办。来自国内外实验动物领域专家 学者、实验动物管理部门领导嘉宾、业内科技工作者以及相关企业代表共700人参加大会。 经中国实验动物学会评选,授予上海两位专家尹松林教授、何新桥研究员2016年中国实验动物学会 终身贡献奖,在此表示衷心祝贺。 (本刊编辑部)
