Anti-MDR1 Antibody, conformational extracellular epitope, clone UIC2

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).

P-glycoprotein encoded by the MDR1 gene (ABCB1; LocusLink ID: 5243)

Epitope: conformational extracellular epitope

Mouse BALB/c 3T3 fibroblasts transfected with human MDR1 cDNA, followed by a multistep selection of tranfectants for resistance to vinblastine.

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).

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.
