摘要: 将感染弓形虫速殖子的SD大鼠血清和健康大鼠血清作为一抗进行蛋白质印迹(Western blotting)分析,比较杂交蛋白点的差异,分析弓形虫速殖子特异性抗原。弓形虫速殖子总蛋白双向电泳考马斯亮蓝染色图谱(7 cm×8 cm, pH 3~10)共检测到209个蛋白质斑点。Western blotting显示实验组抗原抗体反应点17个,对照组仅2个非特异性的蛋白结合点。

Abstract: The total protein of Toxoplasma gondii RH strain tachyzoites was separated by two-dimensional electrophoresis (2-DE), and Western blotting was performed to find out distinct antigens. 209 spots were detected through Coomassie brilliant blue-stained small gels (7×8 cm, pH 3-10). Western blotting showed 17 specific antigen spots with sera of the experimental group and two nonspecific spots with the control sera.
