Human Transporter MRP2 Fluorescence-based Antagonist Assay Service

Human Transporter MRP2 Fluorescence-based Antagonist Assay is a laboratory test used to evaluate the inhibitory effects of a substance on the multidrug resistance protein 2 (MRP2) transporter in human cells. MRP2 is a membrane protein that plays a key role in the transport of various drugs and toxins out of cells, thus contributing to drug resistance in cancer cells and other cell types.

MRP2

MRP2 protein, also known as Multidrug Resistance-Associated Protein 2, is a transmembrane protein that is involved in the transport of a wide range of endogenous and xenobiotic substrates across the cell membrane. It is a member of the ATP-binding cassette (ABC) transporter family and is primarily expressed in the liver, kidneys, and intestines. MRP2 plays a crucial role in the elimination of toxic compounds and metabolites from the body by transporting them out of cells and into bile or urine for excretion. It is also involved in the transport of a variety of drugs, leading to multidrug resistance in cancer cells and affecting the pharmacokinetics of various medications.

Our Service

In this assay, human cells expressing MRP2 are exposed to a known substrate of the transporter, such as 5(6)-carboxy-2',7'-dichlorofluorescein (CDCF). The test substance being evaluated for its antagonist effects on MRP2 is added to the cells, and the intracellular accumulation of the substrate is measured using fluorescence detection methods. By quantifying the levels of the substrate inside the cells in the presence of the test substance, you can determine the ability of the substance to inhibit the transport function of MRP2.
