Multi-Drug Resistance Assay Kit (Green)

Cat.No.: Kit-0546
Product Overview: Multi-Drug Resistance Assay Kit use a fluorescent MDR indicator for assaying two ATP-dependent drug-efflux pump activities.
Description: Multi Drug Resistance (MDR) is a major factor in the failure of many forms of chemotherapy. In the past few years it has become widely accepted that the resistance to chemotherapy correlates with the overexpression of at least two ATP- dependent drug-efflux pumps. These cell membrane proteins, called P-glycoprotein (Pgp, MDR1), and multidrug- resistance-associated protein (MRP1) are members of the ABC transporter family. Our Multi-Drug Resistance Assay Kit (Green) uses a fluorescent MDR indicator for assaying these two MDR pump activities. This hydrophobic fluorescent dye molecule rapidly penetrates cell membranes and becomes trapped in cells. Following a short incubation, the intracellular free dye concentration can increase significantly. In the MDR1 and/or MRP1-expressing cells this dye is extruded by the MDR transporters, thus decreasing the cellular fluorescence intensity. However, when its extrusion is blocked by an agent that interferes with the MDR1 and/or MRP1 pump-activity, its cellular fluorescence intensity increases significantly. Multi-Drug Resistance Assay Kit (Green) are ideal for high throughput screening of MDR pump inhibitors or identifying the cells that have high level of MDR pump activities.
