  • Function
    Secretogranin-1 is a neuroendocrine secretory granule protein, which may be the precursor for other biologically active peptides.
  • Tissue specificity
    Expressed in the adrenal medulla, and in pheochromocytoma. Not expressed in liver.
  • Sequence similarities
    Belongs 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 localization
    Secreted. Neuroendocrine and endocrine secretory granules.

  • ab12242(1:1000) staining Chromogranin B in human pancreas (IgG inset) using an automated system (DAKO Autostainer Plus). Using this protocol there is strong staining of Chromogranin B in secretory compartments of the pancreas.
    Insert panel depicts negative control (no primary antibody).
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH9.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX.
    Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.

This product is sold as whole antiserum, not as purified antibody. In general, we estimate that the total Ig concentration in serum is approx. 10 mg/ml, and the specific antibody component is approx. 10% of this. I hope this helps.

Thank you for your enquiry. This product is whole, undiluted antiserum, so it is not in a storage buffer. To dilute for use, we recommend either PBS or a buffer/medium that is compatible with the user's assay system.
