FLAG® 纯化

FLAG®标签能对重组融合蛋白进行出色的检测和稳健的纯化,在从结合和活性检测到结构分析的众多下游应用中都得到了验证。FLAG® 表位标签是一种短小、亲水性强的八氨基酸肽(DYKDDDDK 标签),很容易被肠激酶(EK)裂解。由于 FLAG® 标签体积小且具有亲水性,因此通常位于融合蛋白的表面,从而最大限度地减少了对融合蛋白功能、分泌或运输的影响。无论您的最终应用是什么,我们都能提供表达、纯化和检测 FLAG® 融合蛋白所需的工具。

- User Guide: FLAG - Proven System for Detection and Purification of Proteins
The FLAG Expression System is an established way to express, purify, and detect recombinant fusion proteins. FLAG and 3×FLAG® have proven utility in numerous applications such as Western blotting, immunocytochemistry, immunoprecipitation, flow cytometry, protein purification, and in the study of protein-protein interactions, cell ultrastructure, and protein localization. These small hydrophilic tags facilitate superior detection and purification of recombinant fusion proteins when using our highly specific and sensitive ANTI-FLAG® antibodies.
