ETEC K99、K88菌毛蛋白抗原表位多肽的设计合成及免疫反应
Design Synthesis and Immunological Reaction of Epitope Peptides of ETEC K88 and K99 Fimbrial Protein
摘要
Abstract
In order to investigate the epitopes of ETEC K88 and K99 fimbrial protein, we designed and synthesized the epitope peptides of ETEC K88 and K99 fimbrial protein by bioinformatical and structural analysis software. The epitope peptides of ETEC K88 and K99 fimbrial protein were designed and synthesized after predicting and analyzing the relational parameters of the antigeni-city of ETEC K88 and K99 fimbrial protein with bioinformatics, DNAStar Protean and online sharing software. C57BL/6 mice were immunized with these synthetic peptides, the antibodies in serum were measured by ELJSA, and the challenge test was implemented on the immune mice. The results showed that two synthetic peptides could induce high titers of specific antibodies after immunological reaction. The results of challenge test with C83912 or C83902 showed that protection activity was found in the mice immunized with these synthetic peptides. It was concluded that the epitopes were successfully predicted, and the synthetic epitope peptides showed high antigenicity.关键词
