The conditions of expression and purification of sed protein were optimized . then we detected the mitogen activity and tcrv specificity of sed with human pbmc and mice plenocytes . the results showed that the expressed sed have superantigenic activity 构建sed的原核表达系统，并对蛋白的表达和纯化条件进行优化，用两种系统即人的pbmc和小鼠脾脏细胞，检测了纯化sed的促t淋巴细胞增殖活性和tcrv6特异性。
In this study , we transformed the vp1 gene of fmdv serotype o into the tobacco chloroplast and chlamydomonas reinhardtii chloroplast , and achieved highly expression levels , paving the way for engineering an fmdv vaccine via transplastomic plants 在本文中作者将o型口蹄疫病毒vp1抗原基因分别重组和转化到模式植物烟草和衣藻的叶绿体基因组中，并使其得到高效表达，为利用植物叶绿体表达系统生产口蹄疫基因工程疫苗提供了技术依据。
