解剖和研究细胞系统需要能够特异性分离不同的蛋白质及其相关复合物的共组装成分。亲和捕获技术利用高亲和力、高特异性试剂来靶向和捕获感兴趣的蛋白质以及细胞提取物中的特异性相关蛋白质。亲和捕获与基于质谱 (MS) 的蛋白质组分析相结合,能够分离和表征各种内源蛋白质复合物。在这里,我们概述了蛋白质复合物亲和捕获的有效程序,重点介绍了最佳实践和常见陷阱。
Dissecting and studying cellular systems requires the ability to specifically isolate distinct proteins along with the co-assembled constituents of their associated complexes. Affinity capture techniques leverage high affinity, high specificity reagents to target and capture proteins of interest along with specifically associated proteins from cell extracts. Affinity capture coupled to mass spectrometry (MS)-based proteomic analyses has enabled the isolation and characterization of a wide range of endogenous protein complexes. Here, we outline effective procedures for the affinity capture of protein complexes, highlighting best practices and common pitfalls.
