|General bioluminescence reaction of coelenterazine|
The BRET method has seen several modifications over the years including NanoBRET which was discussed in a BMG LABTECH webinar last year. However, a recent JBC paper employs the classic BRET approach to analyze the interaction of the long-chain fatty acid receptor, FFA4, with beta-arrestin in order to study which ligands bind to FFA4.
This analysis employed the PHERAstar FS from BMG LABTECH. When the FS is equipped with BRET 1 optic module it can perform simultaneous dual emission detection and measure the luminescent emission at 530 and 490 nm produced by YFP and Rluc respectively.
