P-glycoprotein antibody

Antigen: P-glycoprotein

Clonality: Monoclonal (17F9)

Host: Mouse

Reactivity: Human

Application: Flow Cytometry (FACS), Immunoprecipitation (IP), Western Blotting (WB)

Catalog no.: ABIN967562

Additional Information

Format: Liquid

Isotype: IgG2b, kappa

Clone: 17F9

Description: Reacts with a 170-180 kDa transmembrane glycoprotein (P-glycoprotein), a product of the multidrug resistance-1 (MDR1) gene. This glycoprotein is expressed on MDR positive cells and has been reported to be expressed on many normal tissues, such as adrenal glands and endothelium, in the brain and skin. P-glycoprotein is known to impart drug resistance to cells by pumping many anti-cancer drugs out of the cytoplasm. 17F9 antibody binds to the surface of the viable, unfixed MDR+ cell line, PMG-Y (please inquire), and is able to partially block the binding of UIC2 antibody (another MDR-specific monoclonal antibody). Immunoprecipitation application is reported, but not routinely tested in house.
Synonyms: MDR

Characteristics: 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
