General description

Rhodamine 110 or R110 is a triphenylmethane dye and emits a strong green-fluorescent light. The high fluorescence is attributed to the presence of amino groups as electron donating groups. Rhodamine 110 has excitation and emission maximum at 502.4/521.6 nm, respectively.

Application

Rhodamine 110 is used for the determination of protease activity with accurate kinetic parameters. It is used to measure caspase activity in cells with induced apoptosis.
