Rhodamine 123 is a membrane-permeable cationic dye that is readily accumulated within living cells.{27856} 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.{27854,27855} 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.{27855,27857} Rhodamine 123 also accumulates within mitochondria due to its positive charge and can inhibit oxidative phosphorylation.{27856,27853} Rhodamine 123 has excitation/emission maxima of 507/529 nm.{42160}
