Rhodamine 110 (chloride)

Rhodamine 110 is a green fluorescent cationic dye with excitation and emission maxima of 496 and 520 nm, respectively. When incorporated with a hydrolytic substrate (e.g., proteinase or peptidase substrates), it can be used as a highly sensitive detection reagent in fluorescence-based enzyme assays. Rhodamine 110 has also been used in a fluorescence quenching method for determining trace nitrite and as a probe for cytochrome P450 activity.Formal Name: 3,6-diamino-9-(2-carboxyphenyl)-xanthylium, monochloride.
