鹅细小病毒非结构蛋白和结构蛋白B细胞线性抗原表位的鉴定
Localization of Linear B-cell Epitopes on Goose Parvovirus Non-structural Protein and Structural Protein
【摘要】 鹅细小病毒是小鹅瘟的病原体,其基因组含有2个主要开放阅读框(ORF),分别编码非结构蛋白(NS)和结构蛋白(VP)。为了对这2种蛋白进行抗原表位作图,设计了34个覆盖非结构蛋白NS和结构蛋白VP的50~60个氨基酸残基的重叠短肽,并进行了融合表达。用攻毒10周龄鹅血清对这34个融合蛋白进行蛋白质印迹分析,结果鉴定出NS蛋白线性抗原表位位于C末端的453-627氨基酸区域;VP蛋白线性抗原表位位于35—198、423—491、531—595、616—669和678—732氨基酸区域。
【Abstract】 The non-structural protein and structural protein of goose parvovirus were dissected into 15 or 19 fragments,respectively,and expressed in Escherichia coli.Then Western blot reactivity of these short peptide fused proteins were surveyed by using viral infected sera.The results showed that the non-structural protein linear B-cell epitopes are located on the C-terminal(453-627 aa) and the structural protein linear B-cell epitopes are located on 35-198,423-491,531-595,616-669,678-732 aa.
