  • Function
    Cardiac hormone which may function as a paracrine antifibrotic factor in the heart. Also plays a key role in cardiovascular homeostasis through natriuresis, diuresis, vasorelaxation, and inhibition of renin and aldosterone secretion. Specifically binds and stimulates the cGMP production of the NPR1 receptor. Binds the clearance receptor NPR3.
  • Tissue specificity
    Brain and also in atria, but at much lower levels than ANP.
  • Sequence similarities
    Belongs to the natriuretic peptide family.
  • Cellular localization
  • Information by UniProt
  • Database links

  • proBNP was immunoprecipitated from 7x106 HCT116 (human colon carcinoma cell line) cells with ab26 at 1/150 dilution. Western blot was performed from the immunoprecipitate using anti-p53 antibody. Donkey Anti-Mouse IgG H&L (Alexa Fluor® 750) preadsorbed (ab175739) was used as secondary antibody at 1/5000 dilution.

Customer reviews and Q&As


Thank you very much for your inquiry.

I have to confirm that do not have any pro-BNP antibodies that are tested and guaranteed for rat.

I checked the immunogens for the available pro-BNP antibodies and unfortunately I cannot recommend any of for testing in rat.

We usually expect an cross-reaction when the homology is 85% and higher. But the different regions that the immunogens are taken from only show 62% and less homology:

AA 1-12 no homology
AA 13-27 58%
AA 28-45 62%
AA 61-76 no homology.

I am sorry I could not be of more help on thisoccasion and wish you goo dluck with your research.
