丙型肝炎病毒 ( HCV)包膜蛋白 E2是一种可作为HCV疫苗侯选抗原的病毒体表面糖蛋白。E2蛋白生物活性形式的鉴定将有助于 HCV疫苗的研制。作者对胞内型及分泌型 HCV E2糖蛋白的功能特征进行了研究。将编码 E2 661蛋白的真核表达载体 p14.t E2 . 661.hiv转染 HEK- 2 93细胞 ,分别 Hepatitis C virus (HCV) envelope protein E2 is a virion surface glycoprotein that acts as a candidate antigen for the HCV vaccine. The identification of the biologically active form of the E2 protein will contribute to the development of the HCV vaccine. The authors studied the functional characteristics of the intracellular and secreted HCV E2 glycoproteins. The E2 661 protein eukaryotic expression vector p14.t E2. 661.hiv was transfected into HEK-2 93 cells, respectively
