拉下实验（Pull-down）的缺点 1、两个非同一定位的蛋白可能因电荷或是强亲和力的原因造成假阳性，需用其他方法再次验证，例如Co-IP等；2、验证互作是在试管中进行的生化反应，不能够完全反映细胞内蛋白真实互作的状态；3、融合表达的GST标签，肽链较长，可能会改变原目的蛋白的原有的折叠结构。实验信息 实验过程中...
Characterizing Protein Complexes: GST Pull-Down assays can be used to isolate and characterize multi-protein complexes. By using GST-tagged components of the complex as bait, researchers can identify other proteins that are part of the same complex. Functional Studies: These assays can be used to...
GST Pull Down ServiceGST Pull-Down Assays ServiceMany proteins function in association with partner proteins or as components of large multiprotein complexes. Understanding these protein interactions is critical to our understanding of biological pathways and cellular function.The...

Pull-down assays, including GST pull-down, can effectively validate direct protein-protein interactions. This method provides clear, reliable evidence of interactions between proteins, which is crucial for understanding biological processes. 2. How do I choose the appropriate tag for my proteins in a...

The following protocol provides general guidelines for GST pull-down assays using the MagneGST™ Pull-Down System and is based on methods we have developed using a MyoD/GST-Id protein pair. Optimization of protein- protein interaction and washing conditions may be required for each bait-prey ...
Pull-down是一种小规模亲和纯化技术,与免疫沉淀反应类似,但其抗体功能被某些其他亲和系统代替。在这种情况下,亲和系统是一种可被谷胱甘肽琼脂糖微珠捕获的 GST 标签蛋白。融合标记蛋白质作为捕获推定连结配偶体(即猎物)的诱饵。在典型的pull-down 试验中,固定的诱饵蛋白质与细胞裂解液一起孵育。在规定的洗涤步骤后,...
