What is the Rhodamine 123 ?

Rhodamine 123 is Red to brown powder., while it's Molecular Formula is C21H17ClN2O3. Rhodamine-123 is a fluorescent dye most commonly used in flow cytometry as functional reporter for Pgp. Rhodamine 123 (R123), as a typical of P-glycoprotein substrate, was widely used to quantify P-glycoprotein (P-gp) functional efflux activity in vivo. Rhodamine-123 can be used in multiparameter analyses without fluorescence interference in combination with common protein labeling dyes such as PE-Cy5 and AMCA (7-amino-4-methylcoumarin-3-acetic acid).

What is Rhodamine 123 (62669-70-9) used for?

Rhodamine 123 is a membrane-permeable cationic dye that is readily accumulated within living cells. It is a substrate for the efflux pump P-glycoprotein (P-gp; also known as multidrug resistance protein 1 and ABCB1) and is rapidly exported from cells with functional P-gp. As P-gp is expressed on a population of stem cells known as the side population, rhodamine 123 is used to detect this group of stem cells. Rhodamine 123 also accumulates within mitochondria due to its positive charge and can inhibit oxidative phosphorylation. Rhodamine 123 has excitation/emission maxima of 507/529 nm.
