napheamal

Naph-EA-mal (Thiol-green 1) is a highly efficient and quick-responding thiol fluorescence probe specifically designed for protein labeling and bioimaging applications. This compound offers a rapid detection method and exhibits ultrafast turn-on fluorescence upon interaction with thiols. Naph-EA-mal (Thiol-green 1) enables the detection of thiols in live cells, facilitates the labeling of protein thiols, enables quantification of total thiol concentration in cell lysate, and allows for the determination of reversible protein thiol oxidation in fixed cells. It possesses an excitation wavelength of 488 nM and an emission wavelength of 540 nM.
