Flow Cyt
  • Application notes
    Flow Cyt: 1/200 (PMID 18192083).
    ICC/IF: 1/300 (PMID 18192083).
    ICC: 1/200.
    IHC-P: 1/4000.
    IHC-Fr: Suggested working dilution of 1/300 (see PMID: 17043672).
    WB: 1/5000. Predicted molecular weight: 118 kDa. Can be blocked with Natriuretic Peptide Receptor A peptide (294-308) (ab28437). In the Tian et al. paper, the membrane was blocked in 20% non-fat milk and the primary and secondary antibody was also diluted in 10% non-fat milk to reduce the background.

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function
      Receptor for the atrial natriuretic peptide NPPA/ANP and the brain natriuretic peptide NPPB/BNP which are potent vasoactive hormones playing a key role in cardiovascular homeostasis. Has guanylate cyclase activity upon binding of the ligand.
    • Sequence similarities
      Belongs to the adenylyl cyclase class-4/guanylyl cyclase family.
      Contains 1 guanylate cyclase domain.
      Contains 1 protein kinase domain.
    • Post-translational
      Phosphorylation of the protein kinase-like domain is required for full activation by ANP.

    • ICC/IF image of ab14356 stained MCF7 cells. The cells were 4% PFA 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 (ab14356, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 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.

    Thank you for getting back to me. I am pleased that you have published your data. Thank you very much for getting back to me. I have added this publication to the references specific for this antibody.

    I'm sorry to hear you are having a problem with ab14356. Typically, an entirely black blot would mean that there is not enough blocking or far too much protein or antibody. A recent reviewer suggested that the antibody worked well although they did...
