The GloSensor technology from Promega is based on a biosensor protein expressed from a genetically modified form of luciferase. This biosensor is capable of modulating its luminescence activity dependent on reversible allosteric interaction with ligand allowing live-cell, real-time monitoring of cAMP kinetics and allows investigation of both endogenous and over-expressed GPCR targets.

This file illustrates the reading parameters used for an end-point luminescence GloSensor assay, as well as Gen5’s ability to plot titration curves using a 4-parameter fit and to calculate EC50 values.
