| Biochem/physiol Actions: | Overexpression of ABCB1 (ATP binding cassette subfamily B member 1) gene is a major cause for multi-drug resistance, which makes chemotherapy challenging for the treatment of osteosarcoma. P-glycoprotein (P-gp) mediates the energy-dependent efflux of xenobiotic to the outside of plasma membrane from the inside of the cell , thereby affecting the process of absorption, distribution, and excretion of drugs. Cyclosporine, a calcineurin inhibitor serves as a substrate for P-gp. |
| Biochem/physiol Actions: | The antibody recognizes an epitope located in the amino terminal half of P-glycoprotein (Pgp), at the third extracellular loop of the molecule. The epitope is resistant to formalin fixation and periodate oxidation. The antibody detects specifically human MDR1 P-glycoprotein, but does not appear to recognize the human MDR3 product, nor the mouse mdr1a, mdr1b or the mdr3 P-glycoprotein. |

| General description: | The ABCB1 (ATP binding cassette subfamily B member 1) gene is mapped to human chromosome 7q21.12. It encodes for P-glycoprotein, which is a membrane bound drug transporter protein, belonging to the ATP-binding cassette (ABC) transporters family. The gene is considered to be highly polymorphic. |
| Immunogen: | mixture of human and hamster drug-resistant whole cells and crude plasma membranes. |
