Description_x000D_ General description_x000D_ Multidrug resistance associated protein 1 (MRP1) is present in subcellular vesicles and is composed of 1531 amino acids. It has a molecular weight of 190kDa. The gene encoding MRP1 is localized in human chromosome 16p13.11._x000D_ Specificity_x000D_ Does not cross-react with the human MDR1 and MDR3 proteins._x000D_ Immunogen_x000D_ non-denatured membrane preparations of H69AR human small cell lung cancer cell line, which highly expresses MRP1. The epitope resides within the second nucleotide-binding domain of human MRP1 between amino acids 1294-1531._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Packaging_x000D_ 200 μL in glass bottle_x000D_ Biochem/physiol Actions_x000D_ Multidrug resistance associated protein 1 (MRP1) functions in the metabolism of many drugs. It is involved in transporting different biomolecules and anticancer drugs like prostaglandins, glutathione, alkaloids and anthracyclines. MRP1 offers resistance against chemotherapy to cells in solid tumors.
