Gst pull down 结果图
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 ...
