    • PURPOSE: A porcine kidney epithelial cell line for replication of virus and the use thereof are provided. The porcine kidney epithelial cell line has improved infectivity titer and the influenza virus produced from the porcine kidney epithelial cell line does not induce antigenic change of the HA1 region of hemagglutin molecule. Therefore, it can be useful for production of influenza virus vaccine for human and animals. CONSTITUTION: A porcine kidney epithelial cell line(VL-PKEC)(KCTC 10299BP) for replication of virus is free of HA antigenic change. The virus is Japanese encephalitis virus, porcine circovirus or influenza virus, and the influenza virus comprises all subtypes of influenza viruses. A method for replication of virus without HA antigenic change comprises the steps of: (a) infecting a virus to be replicated with the porcine kidney epithelial cell line(VL-PKEC)(KCTC 10299BP); (b) culturing the infected virus; and (c) isolating and purifying the virus when the virus shows high titer.
    • 目的:提供用于病毒复制的猪肾上皮细胞系及其用途。 猪肾上皮细胞系具有改善的感染效价,并且由猪肾上皮细胞系产生的流感病毒不诱导血凝素分子的HA1区域的抗原性变化。 因此,它可用于生产用于人和动物的流感病毒疫苗。 构成:用于病毒复制的猪肾上皮细胞系(VL-PKEC)(KCTC 10299BP)不具有HA抗原性变化。 病毒是日本脑炎病毒,猪圆环病毒或流感病毒,流感病毒包括流感病毒的所有亚型。 用于复制没有HA抗原变化的病毒的方法包括以下步骤:(a)感染用猪肾上皮细胞系(VL-PKEC)(KCTC 10299BP)复制的病毒; (b)培养感染病毒; 和(c)当病毒显示高滴度时分离和纯化病毒。
