Bioluminescence resonance energy transfer (BRET) allows to quantitate protein interactions in intact cells. Here, we present a protocol for measuring BRET due to transient interactions of oncogenic K-RasG12V in plasma membrane nanoclusters of HEK293-EBNA cells. We describe steps for seeding, transfecting, and replating cells. We then detail procedures for their preparation for BRET measurements on a CLARIOstar microplate reader and detailed data analysis. For complete details on the use and execution of this protocol, please refer to Steffen et al..
生物发光共振能量转移(BRET)可用于定量完整细胞中的蛋白质相互作用。在此,我们展示了一种用于测量由于致癌性K-RasG12V在HEK293-EBNA细胞的质膜纳米簇中的瞬时相互作用而产生的BRET的方案。我们描述了细胞接种、转染和重新铺板的步骤。然后,我们详细说明了在CLARIOstar微孔板读数仪上进行BRET测量的细胞准备程序以及详细的数据分析。有关此方案的使用和执行的完整详细信息,请参考斯特芬等人的研究。
