This clone recognizes an internal, highly conserved amino acid sequence (VQEALD and VQAALD) found in both protein isoforms, MDR1 P-glycoprotein (~170kDa) and MDR3 P-glycoprotein (~140kDa). In Western blot, boiling samples may reduce visibility of the protein.
For flow cytometry, cells should be fixed in 3.7% formaldehyde for 10 min at room temperature to permeabilize the cell membrane. Incubate cells with 5-10 µg antibody for 30-60 min at 4°C.
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.
