• Product nameAnti-MRP2 antibody [M2 III-6]
    See all MRP2 primary antibodies
  • Description
    Mouse 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, ICC, IHC-P, IHC-Fr, WBmore details
  • Species reactivity
    Reacts with: Human
    Predicted to work with: Dog
  • Immunogen

    Bacterial fusion protein of human MRP 2 containing the carboxy-terminal region (residues 1339-1541).

  • EpitopeThis antibody reacts with an internal epitope of MRP 2.
  • General notes

    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.



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.

Application Abreviews Notes
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
ICC 1/20 - 1/50.

Acetone fixed cytospin preparations.

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.
IHC-Fr 1/20.

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).
The protein is glycosylated at amino acid 7, 12 and 1011 so higher band size is expected.


  • 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.
