| Description | Anti-MDR1 Antibody, clone UIC2, azide free |
| Alternate Names |
|
| Background Information | UIC2 is a mouse monoclonal antibody directed against the extracellular conformational epitope of P-glycoprotein (Pgp). This antibody can be used in flow cytometry, immunofluorescence microscopy and immunohistochemistry in frozen and paraffin sections to detect Pgp expression on the membrane of MDR1 positive cells. In functional experiments, UIC2 was shown to inhibit Pgp-mediated efflux activity and potentiate the cytotoxic effects of chemotherapy drugs transported by Pgp. Additionally, the UIC2 monoclonal antibody can be used in combination with MDR1 substrates for simulatenaeous detection of Pgp expression and function by flow cytometry (MILLIPOREs UIC2 Shift assay - see product ECM905). |

| Entrez Gene Number |
|
| Entrez Gene Summary | The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance. The protein encoded by this gene is an ATP-dependent drug efflux pump for xenobiotic compounds with broad substrate specificity. It is responsible for decreased drug accumulation in multidrug-resistant cells and often mediates the development of resistance to anticancer drugs. This protein also functions as a transporter in the blood-brain barrier. |
