Protein–protein interactions (PPIs) play central roles in most molecular mechanisms underlying cellular and biological processes. Within the methods developed to study PPIs is bioluminescence resonance energy transfer (BRET). Taking advantage of this technique, we have set a BRET-based assay that enables the screening of modulators of essential PPIs for Trypanosoma cruzi survival. Considering the complexity of the evaluated mixture, pure chemical compounds or natural extracts, two approaches are described, BRET in living cells or from lysates.
