  • 功能Secretogranin-1 is a neuroendocrine secretory granule protein, which may be the precursor for other biologically active peptides.
  • 组织特异性Expressed in the adrenal medulla, and in pheochromocytoma. Not expressed in liver.
  • 序列相似性Belongs to the chromogranin/secretogranin protein family.
  • 翻译后修饰Extensively processed by limited proteolysis at conserved basic residues. Alternative processing are seen in different tissues.

Anti-Chromogranin B antibody 图像

  • 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.
