Description
Catalogue Number MAB4334
Brand Family Chemicon®
Trade Name
  • Chemicon
Description Anti-MDR1 Antibody, conformational extracellular epitope, clone UIC2
Alternate Names
  • P-glycoprotein
  • CD243
  • p170
  • Pgp
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 (MILLIPORE's UIC2 Shift assay - see product ECM905).

Product Information
Format Purified
Presentation The immunoglobulin was purified by protein A Sepharose™ chromatography and is presented as a liquid in in 0.1M PBS, containing 0.1% sodium azide as a preservative.
Applications
Application Anti-MDR1 Antibody, conformational extracellular epitope, clone UIC2 detects level of MDR1 & has been published & validated for use in FC, IF, IP, IH, IH(P).
Key Applications
  • Flow Cytometry
  • Immunofluorescence
  • Immunoprecipitation
  • Immunohistochemistry
  • Immunohistochemistry (Paraffin)
  • Affects Function
Application Notes Inhibition of P-glycoprotein efflux activity in functional experiments: 10 - 100 μg/mL, varies in different systems.

Immunoprecipitation: 5 - 10 fold molar excess of UIC2 over the expected Pgp concentration; realistically, 1 - 5 μg per 1 mL of cell lysate.

Flow Cytometry (conventional and UIC2 Shift assay): depends highly on Pgp expression by target cells; usually, 0.1 μg/mL for low Pgp expressors and 1 μg/mL for high Pgp expressors.

Immunofluorescence: depends highly on Pgp expression by target cells; usually, 0.1 ug/ml for low Pgp expressors and 1 μg/mL for high Pgp expressors.

IHC on frozen and paraffin sections: 1 - 10 μg/mL.

Optimal working dilutions must be determined by end user.

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.
