Real Thiol is a reversible reaction-based fluorescent probe which can quantitatively monitor the real-time glutathione dynamics in living cells. In Vitro: Real Thiol (RT) shows ratiometric fluorescence responses with a wide dynamic range when reacting with Glutathione (GSH). Real Thiol and its GSH adduct (RT-GSH) shows fluorescence maxima at 487 and 562?nm with excitation wavelengths at 405 and 488?nm, respectively. The K_d for the reaction between Real Thiol and GSH is 3.7?mM. Real Thiol has much improved quantum yields and photostability. The wide dynamic range of Real Thiol allows for monitoring of the GSH level changes within 1 to 10?mM in both directions in living cells. Gel permeation chromatography (GPC) analysis showes that 10% of Real Thiol reacts with thiolated proteins while 90% of Real Thiol reacts with GSH^[1].
