Application Abreviews Notes
ICC/IF 1/200.
IP 1/1000 - 1/10000. Blocking with 5% goat or donkey serum significantly reduces background when compared with BSA or milk blocking.


  • FunctionHormone playing a key role in cardiovascular homeostasis through regulation of natriuresis, diuresis, and vasodilation. Also plays a role in female pregnancy by promoting trophoblast invasion and spiral artery remodeling in uterus. Specifically binds and stimulates the cGMP production of the NPR1 receptor. Binds the clearance receptor NPR3.
  • Involvement in diseaseAtrial standstill 2
    Atrial fibrillation, familial, 6
  • Sequence similaritiesBelongs to the natriuretic peptide family.
  • Post-translational
    Cleaved by CORIN upon secretion to produce the functional hormone.
    Atrial natriuretic factor: Cleaved by MME. The cleavage initiates degradation of the factor and thereby regulate its activity.

Anti-ANP antibody images

  • ICC/IF image of ab40791 stained DU145 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab40791 at 1/200 dilution overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
