IHC-P Use a concentration of 5 µg/ml.


  • FunctionSecretogranin-1 is a neuroendocrine secretory granule protein, which may be the precursor for other biologically active peptides.
  • Tissue specificityExpressed in the adrenal medulla, and in pheochromocytoma. Not expressed in liver.
  • Sequence similaritiesBelongs to the chromogranin/secretogranin protein family.
  • Post-translational
    Extensively processed by limited proteolysis at conserved basic residues. Alternative processing are seen in different tissues.
  • Cellular localizationSecreted. Neuroendocrine and endocrine secretory granules.

  • IHC image of Chromogranin B staining in Rat normal brain formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab85286, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

  • ICC/IF image of ab85286 stained PC12 cells. The cells were 4% paraformaldehyde 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 (ab85286, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit 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.
