抄録

We developed a new assay of Bcl-x_L inhibitors based on fluorescence resonance energy transfer that occurs between an AEDANS-labeled Bak-BH3 peptide and three tryptophans in the BH1 and BH2 domains of Bcl-x_L. The method can tolerate up to 5% DMSO, and it was validated with several Bcl-x_L inhibitors. It can be adapted to screen for compounds targeting other Bcl-2 family proteins.
