Abstract
P-glycoprotein (P-gp) is involved in the transport of a wide variety of organic compounds including a fluorescent dye, rhodamine 6G (RG), as well as anti-cancer drugs. Agents that overcome classical multidrugresistance (MDR) increased the accumulation of RG in an MDR cell line, KB-C1. The effect of agents on RG-accumulation in KB-C1 cells was highly correlated with their effect on the reversion of vincristine-resistance in KB-C1 cells. RG was detected on a fluorescence microplate reader with a rhodamine channel. This assay may become a useful method for the screening of agents that overcome classical MBR, since it is quick and simple.
