General description

The 72 kDa breast cancer resistance protein (BCRP) is the second member of the subfamily G of the human ATP binding cassette (ABC) transporter superfamily and thus also designated as ABCG2. BCRP is a half-transporter consisting of only 1 nucleotide binding domain followed by 1 membrane-spanning domain. Current experimental evidence suggests that BCRP may function as a homodimer or homotetramer. Overexpression of BCRP is associated with high levels of resistance to a variety of anticancer agents. BCRP expression has been detected in a large number of hematological malignancies and solid tumors, indicating that this transporter may play an important role in clinical drug resistance of cancers. In addition to its role to confer resistance against chemotherapeutic agents, BCRP actively transports structurally diverse organic molecules, conjugated or unconjugated, such as estrone-3-sulfate, 17-β-estradiol 17-(β-D-glucuronide), and methotrexate. BCRP is highly expressed in the placental syncytiotrophoblasts, in the apical membrane of the epithelium in the small intestine, in the liver canalicular membrane, and at the luminal surface of the endothelial cells of human brain microvessels. This strategic and substantial tissue localization indicates that BCRP also plays an important role in absorption, distribution, and elimination of drugs that are BCRP substrates.

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.

Physical form

Liquid containing 0.7% BSA and 0.1% sodium azide.

Specificity

This antibody reacts with an internal epitope of the Breast Cancer Resistance Protein (BCRP), a 70 kDa transmembrane half-transporter which is involved in multidrug resistance. The antibody does not cross-react with human MDR1, MRP1, MRP2 or MRP5 gene products.

Storage and Stability

Maintain refrigerated at 2-8°C for up to 6 months. For long-term storage store at -20°C.
