摘要: 本研究以不同纤维直径的细毛羊皮肤组织中的毛囊作为试验材料,利用不同的提取方法、不同pH范围的IPG胶条以及不同的上样量,探索适用于细毛羊皮肤组织的双向电泳体系,建立细毛羊皮肤组织毛囊的2-DE凝胶图谱.凝胶图谱用ImageMaster 2D Platinum软件自动检测蛋白点比较不同纤维直径的细毛羊差异蛋白.结果显示,TCA/丙酮抽提法最适合细毛羊毛囊组织总蛋白质的提取.上样量为100 μL,选择18 cm、pH 4~7的线性IPG胶条,得到质量较好的双向凝胶电泳图谱,有35个蛋白差异点,为后续优质细毛羊的蛋白质组学研究工作奠定基础.

Abstract: In use of hair follicles in skin tissue of fine-wool sheep with different fiber diameters as experimental material, and different extraction methods, IPG strips with different pH and different sample volume as experimental methods, this paper was aimed to explore two-dimensional electrophoresis system applied to skin tissue of the fine-wool sheep and establish 2-DE gel map of skin tissue in fine-wool sheep.Gel maps using ImageMaster 2D Platinum software automatically detected protein points to compare different protein fiber diameter of fine-wool sheep differences.The results showed that the TCA/acetone extraction method was most suited to fine-wool sheep hair follicle tissue extraction of total protein.Choose to 18 cm, pH 4 to 7 linear IPG strip, we got better quality two-dimensional gel electrophoresis, got 35 protein variations among the different cantons for the follow-up work fine-wool sheep with high quality of the study of proteomics.

Key words: fine-wool sheep; two-dimensional electrophoresis; hair follicles; proteomics
