Affinity purification followed by mass spectrometry has become the technique of choice to identify binding partners in biochemical complexes isolated from a physiologic cellular context. In this report we detail our protocol for tandem affinity purification (TAP) primarily based on the use of the FLAG and HA peptide epitopes, with a particular emphasis on factors affecting yield and specificity, as well as steps to implement an automated version of the TAP procedure. © 2019 by John Wiley & Sons, Inc.
亲和纯化后进行质谱分析已成为从生理细胞环境中分离出的生化复合物中鉴定结合伴侣的首选技术。在本报告中,我们详细介绍了串联亲和纯化(TAP)方案,该方案主要基于FLAG和HA肽表位的使用,特别强调了影响产量和特异性的因素,以及实施TAP程序自动化版本的步骤。© 2019约翰威立父子公司版权所有
