Our Abpromise guarantee covers the use of ab77184 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
WB Use a concentration of 1 - 3 µg/ml. Detects a band of approximately 170 kDa (predicted molecular weight: 150 kDa).
IHC-P Use a concentration of 4 - 6 µg/ml. Perform heat mediated antigen retrieval via the pressure cooker method before commencing with IHC staining protocol.


  • Function

    May be an organic anion pump relevant to cellular detoxification.
  • Tissue specificity

    Widely expressed, with particularly high levels in prostate, but is barely detectable in liver.
  • Sequence similarities

    Belongs to the ABC transporter superfamily. ABCC family. Conjugate transporter (TC 3.A.1.208) subfamily.

Customer reviews and Q&As


Thank you for your inquiry. I am happy to confirm that all these products are suitable for WB and tested and guaranteed.
I suggest ab29889 (Liver (Human) Tissue Lysate - adult normal tissue) as positive control for ab3366, ab3373, ab3375 and ab24102.
https://www.abcam.com/index.html?datasheet=29889 https://www.abcam.com/index.html?datasheet=29889.
MRP4 is barely detectable in liver and therefore I recommend to use ab30304 (Prostate (Human) Tissue Lysate - adult normal tissue) as positive control.
https://www.abcam.com/index.html?datasheet=30304 https://www.abcam.com/index.html?datasheet=30304.
With ab63907 we used ab29745 (Placenta (Human) Tissue Lysate - adult normal tissue) successfully as control.

I hope this information is helpful and wish you good luck with your research.
