  • DualScreen Kit contains the FRET B/G substrate and a cytotoxicity indicator. Both of the two compounds can readily enter the cells. It combines a cytotoxicity readout and the radiometric reporter gene readout of beta-lactamase. Thus can be used to rapid identify false positives due to toxicity and normalize cytotoxic cellular responses. An intact cell membrane and the activity of endogenous esterases are required for the detection.
