摘要:
为了优化东亚飞蝗消化系统双向电泳技术,建立东亚飞蝗消化系统蛋白表达图谱,探讨雌、雄东亚飞蝗消化系统蛋白组分的差异,利用pH值为3~10和pH值为4~7的胶条分别对雌、雄东亚飞蝗消化系统进行双向电泳分析,进行蛋白组学分析.研究结果发现:雌性东亚飞蝗消化系统蛋白种类多于雄性,雌性东亚飞蝗消化系统特异蛋白中偏酸性蛋白数量与偏碱性蛋白相当,而雄性东亚飞蝗消化系统特异蛋白中酸性蛋白多于碱性蛋白.在雌、雄东亚飞蝗消化系统相匹配蛋白中,含量差异达3倍以上的蛋白约占总匹配蛋白的50;.可见,雌、雄东亚飞蝗消化系统蛋白组分存在差异.
Abstract:
Two-dimensional electrophoresis system was optimized and carried out to establish protein expression map of alimentary system from Locusta migratoria manilensis (Meyen) and then the proteomics difference was in-vestigateed between female Locusta migratoria manilensis (Meyen) and male ones. Two-dimensional electrophore-sis was carried in pH 4~7 and pH 3~10 in order to obtain the best condition and to analyze the proteomics differ-ence between female Locusta migratoria manilensis (Meyen) and male ones. It was found that there were more kinds of protein in alimentary system from female Locusta migratoria manilensis than that in male ones. Among the special protein from female Locusta migratoria manilensis, the quantity of acid protein has the similar level with that of alkaline protein while quantity of acid protein is larger than that of alkaline protein in male Locusta migratoria manilensis. In addition, the quantity of the matched protein spots whose abundance in female or male is over 3fold compared with that in male or female is nearly 50; of the total matched protein. Therefore, protein components are different between the alimentary system of male and that of female.
