Chemical structure of Fluorescent probe QG-1

GB40200

Fluorescent probe QG-1

Also known as (E)-2-cyano-3-[7-(diethylamino)-2-oxochromen-3-yl]-N,N-dimethylprop-2-enamide

Fluorescent probe QG-1 is a reversible fluorescence probe, which is suitable for use in the real-time monitoring and quantification of GSH under physiological conditions (Kd value of 2·59 mM)· Moreover, QG-1 exhibits a fast response time (t1/2 = 5·82 sec), displays extremely low cytotoxicity and can be employed to determine the actual GSH variations in HeLa cells
