WebAug 1, 2007 · The pull-down method described in this protocol is fundamentally similar to immunoprecipitation. Immunoprecipitation is based on the ability of an antibody to bind to its antigen in solution, and the subsequent purification of the immunocomplex by collection on protein A- or G-coupled beads. Similarly, the GST pull-down is an affinity capture ...

WebGST pull down实验之蛋白纯化与包涵体复性 ... 以结合GST标签蛋白为例,在将菌体裂解充分后,离心获得上清溶液,将所获得的蛋白溶液过柱,这时用到的柱子可以特异性识别并结合GST标签。继而用缓冲液过柱,即可将没有GST标签的杂蛋白洗去,再用洗脱缓冲液将 ... Web1. GST pull-down通常用来检测大量的非特异性蛋白质与目标蛋白相互作用。GST是一种载体蛋白,可以通过将其连接到表达靶蛋白上,在混合 物中捕获与该靶蛋白有相互作用的其他蛋白质。之后,利用GST标记的固定矩阵,用于分离以GST为基础的复合物。 infosys technical interview questions
