GSTpulldown操作流程 实验目的:体外检测蛋白质与蛋白质之间相互作用。用于验证两个已知蛋白的相互作用,或者筛选与已知蛋白相互作用的未知蛋白。实验原理:利用重组技术将探针蛋白与GST(Glutathione S transferase)融合,融合蛋白通过GST与固相化在载体上的GTH(Glutathione)亲和结合。因此, 2019-04-20 16:22 News WIKI 相关...
GST pull down GST pull down(GST融合蛋白沉降技术)是体外检测蛋白相互作用的常用方法,可验证已知蛋白之间的互作,也可用于筛选与已知蛋白互作的未知蛋白。此方法操作方便,简单易行。 GST pull down实验原理 GST pull down的主要原理是利用DNA重组技术将已知蛋白与GST融合,而融合蛋白通过GST与固化在载体上的GTH(谷...
免疫共沉淀的话蛋白质是处于天然状态,可以分离得到天然状态下相互作用的蛋白复合体。GST pull-down是将GST融合蛋白作为探针固化到凝胶柱上,与溶液中的目的蛋白结合。可以用来确定融合(或探针)蛋白与未知(或靶)蛋白间的新的相互作用。一、免疫共沉淀是以抗体和抗原之间

Solubility of the GST-fusion protein is very important for successful GST pull-down and should be verified before attempting the pull-down experiment. To evaluate solubility, centrifuge a small volume of lysed cells expressing the fusion protein at 16,000 × g for 40 minutes. Analyze both the ...
GST pull-down assay的基本原理 基本原理是将靶蛋白-GST(Glutathione-S-transferase谷胱苷肽巯基转移酶)融合蛋白亲和固化在谷胱甘肽标记的磁珠上,作为与目的蛋白亲和的支撑物,充当一种“诱饵蛋白”,目的蛋白溶液与之孵育,可从中捕获与之相互作用的“捕获蛋白”(目的蛋白),洗脱结合物后通过SDS-PAGE电泳分析 2022-02-...
