實(shí)驗(yàn)原理 |
抗體與細(xì)胞裂解液或上清中相應(yīng)蛋白結(jié)合后,再與蛋白A/G(ProteinA/G)或二抗偶聯(lián)的agarose珠子孵育,得到蛋白復(fù)合物,洗脫蛋白。 |
細(xì)胞裂解液或上清中的GFP融合蛋白與GFP-Trap孵育,得到蛋白復(fù)合物,洗脫蛋白。 |
細(xì)胞非變性條件下裂解,完整胞內(nèi)存在的許多蛋白質(zhì)-蛋白質(zhì)間的相互作用被保留。如果用蛋白質(zhì)X的抗體免疫沉淀X,與X在體內(nèi)結(jié)合的蛋白質(zhì)Y也能沉淀下來。結(jié)合的實(shí)驗(yàn)原理同A/B | |
