摘要:

旨在筛选弓形虫排泄分泌抗原(ESA)中具有强抗原性的蛋白质组分。通过双向电泳和免疫印迹技术,对弓形虫ESA进行分析。结果共筛选到了18个免疫显性蛋白质点,并成功对其中6个具有代表性的蛋白质点进行了质谱鉴定,显示为微线体蛋白1、微线体蛋白4、包囊基质蛋白和14-3-3蛋白,共4种。本研究进一步为弓形虫病的诊断和疫苗研究提供新的实验依据。

Abstract:

The objective of this study was to screen the main immunogenic antigen of Toxoplasma gondii excreted-secreted antigen(ESA).2-DE combined with Western blotting were used to analysis the components of T.gondii ESA.Eighteen positive protein points were detected in this study.Among them,6 protein spots were selected to identify by matrix-assisted laser desorption/lionization time of flight mass spectrometry(MALDI-TOF/TOF),belonging to microneme protein 1,microneme protein 4,cyst matrix protein and 14-3-3 protein.This study provides a new reference for looking for new candidate molecules for prevention and diagnosis of toxoplasmosis.
