摘要:

以广西沼泽型水牛卵泡液为研究对象,用试剂盒免疫去除成熟及未成熟水牛卵泡液高丰度蛋白质后,采用已建立并优化的双向电泳体系对卵泡液蛋白质样品进行分离。软件分析发现,21个差异表达蛋白质与成熟卵泡液相比,10个蛋白质点表达上调,7个蛋白质点表达下调,3个蛋白质点缺失,1个蛋白质点在水牛未成熟卵泡液中特异性表达。经质谱分析,最终鉴定出3个蛋白质点:硫酸化糖蛋白、转铁蛋白和触珠蛋白。该研究成功分离并鉴定的水牛卵泡液差异蛋白质,为揭示水牛卵母细胞发育的微环境及其成熟机制提供试验依据。其中转铁蛋白对于水牛卵泡液的发育成熟具有十分重要的促进作用,而其它2个蛋白质对水牛卵泡液的成熟相关机制还尚未清楚,有待于进一步的试验研究。

Abstract:

This study employed swamp buffalo follicular fluids in Guangxi as the research object.First describes the purification of mature and immature buffalo follicular fluid samples using a ProteoExtractTM Albumin/IgG Removal Kit,it then described the isolation of proteins from these purified mature and immature follicular fluids using the established and optimized 2DE system.Twenty-one different expression protein spots were found with Image Master 2D platinum software,10 of these proteins were up-regulated in immature buffalo follicular fluid,7 proteins were down-regulated,3 proteins deleted and 1 protein specifically expressed.Three proteins were successfully identified by mass spectrometry,they were probably sulfated glycoprotein-2,transferrin and HP protein.In conclusion,a group of different expression proteins from mature and immature buffalo follicular fluids were successfully isolated and identified to provide experimental basis for developmental microenviroment and maturation mechanism in buffalo oocytes.And transferrin played an important role in promoting the maturation of buffalo follicular fluid,while the maturation mechanism of other two proteins in buffalo follicular fluid was still not clear and it needs to be further studied.
