Product nameAnti-MRP2 antibody [M2 III-6]
See all MRP2 primary antibodies
DescriptionMouse monoclonal [M2 III-6] to MRP2
SpecificityThis antibody detects MRP 2. It does not cross-react with human MDR 1, MRP 1, MRP 3 or MRP 5 gene products.
Tested applicationsSuitable for: Flow Cyt, IP, IHC-P, IHC-Fr, WB, ICC/IFmore details
Species reactivityReacts with: Human
Predicted to work with: Dog
Fusion protein corresponding to Human MRP2 aa 1339-1541 (C terminal).
EpitopeThis antibody reacts with an internal epitope of MRP 2.
We received mixed feedback about rat species so we are removing this from tested species list for now. The immunogen is 84% homologous to human protein so theoretically it should cross react however considering the latest customer feedback we no longer guarantee this species.
Storage instructionsShipped at 4°C. Upon delivery aliquot and store at -20°C. Avoid freeze / thaw cycles.
Storage bufferConstituent: 0.7% BSA

Our Abpromise guarantee covers the use of ab3373 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|Flow Cyt||Use at an assay dependent concentration. PubMed: 18929567
ab170191 - Mouse monoclonal IgG2a, is suitable for use as an isotype control with this antibody.
|IP||Use at an assay dependent concentration. PubMed: 16687572|
|IHC-P||1/200. See Abreview. Abreview indicates that several methods of antigen retreival are suitable for this antibody, but heat mediated Ag retrieval in citrate buffer gave optimal results.|
Acetone fixation of frozen sample is recommended.
|WB||1/20 - 1/50. Predicted molecular weight: 174 kDa.
See Scheffer GL et al. 2000.
The samples MUST NOT be boiled before running the gel as multi-pass transmembrane proteins, like MRP2, aggregate severely at high temperatures, which increases as a direct function of temperature. We recommend heating the samples at 60-70C for 15-20 minutes or at 36C for 20 minutes as mentioned in PLoS Pathog 9:e1003244 (2013).
|ICC/IF||1/20 - 1/50.
Acetone fixed cytospin preparations.
FunctionMediates hepatobiliary excretion of numerous organic anions. May function as a cellular cisplatin transporter.
Tissue specificityFound on the apical membrane of polarized cells in liver, kidney and intestine. The highest expression is found in liver.
Involvement in diseaseDefects in ABCC2 are the cause of Dubin-Johnson syndrome (DJS) [MIM:237500]. DJS is an autosomal recessive disorder characterized by conjugated hyperbilirubinemia, an increase in the urinary excretion of coproporphyrin isomer I, deposition of melanin-like pigment in hepatocytes, and prolonged retention of sulfobromophthalein, but otherwise normal liver function.
Sequence similaritiesBelongs to the ABC transporter superfamily. ABCC family. Conjugate transporter (TC 3.A.1.208) subfamily.
Contains 2 ABC transmembrane type-1 domains.
Contains 2 ABC transporter domains.

Lysates/proteins at 20 µg per lane.
Predicted band size: 174 kDa
Lanes 1 - 3: Merged signal (red and green). Green - ab3373 observed at 210 kDa. Red - loading control, ab52866, observed at 50 kDa.
ab3373 was shown to recognize ABCC2 in wild-type A549 cells as signal was lost at the expected MW in ABCC2 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and ABCC2 knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% Milk. Ab3373 and ab52866 (Rabbit anti-alpha Tubulin loading control) were incubated overnight at 4°C at 1/20 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed ab216772 and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed ab216777 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
Confocal micrographs comparing the presence and localization of hepatic markers within a 2D cell culture of human hepatocytes. Staining β-Catenin with ab32572 at 1/100 (Purple) and MRP2 with ab3373 at 1/100 (Yellow).
Cells were fixed for 30 minutes at 4°C in 4% paraformaldehyde (PFA) and washed 3 times with DPBS. Cells were blocked for 1 hour with DPBS containing 1% donkey serum, 1% Triton X-100. Cells were incubated for 1 hour at room temperature with the primary antibodies diluted in the blocking solution. Cells were washed three times with PBS for 30 minutes each. Cells were incubated for 1 hour at room temperature with appropriate secondary antibodies diluted in the blocking solution. Cells were then washed three times with PBS for 30 minutes each and then imaged using an LSM700 laser scanning confocal microscope.
