工作液配制：配制100ml的modified RIPA buffe：1. 称取790mg 的Tris-Base，加到75ml 去离子水中，加入900mg的NaCl，搅拌，直到全部溶解，用HCl调节PH值到7.42. 加10 ml 10%的NP-403. 加2.5 ml 10%的去氧胆酸钠，搅拌，直到溶液澄清4. 加1 ml 100mM的EDTA，用量筒定容到100ml，2-8℃保存5. 理论上，蛋白酶和磷酸酯酶抑制剂应该在使用当天同时加入（抑蛋白酶肽，亮抑酶肽,胃蛋白酶抑制剂各100 μl; PMSF, Na3VO4, NaF各500 μl），但是PMSF在水溶液中很不稳定，30分钟就会降解一半，所以PMSF应该在使用前现加，其他抑制剂成分可以在水溶液中稳定5天。各种成分在工作液中的终浓度： Tris-HCl: 50 mM, pH 7.4 NP-40: 1% 去氧胆酸钠：0.25% ......阅读全文
免疫沉淀－(IP)
实验概要免疫沉淀是一种纯化蛋白质的方法。将我们感兴趣的一种蛋白质的抗体与细胞提取液孵育，以使抗体和蛋白质在溶液中结合。然后用protein A/G 耦合的琼脂糖凝胶，从样品中将抗体/抗原复合物提取出来。这种物理方法可将所需蛋白质从样品中分离。然后样品可以通过SDS-PAGE 进行分离并做 Wes
