Target

  • FunctionPancreastatin strongly inhibits glucose induced insulin release from the pancreas.
  • Sequence similaritiesBelongs to the chromogranin/secretogranin protein family.
  • Post-translational
    modifications
    Sulfated on tyrosine residues and/or contains sulfated glycans.
    O-glycosylated with core 1 or possibly core 8 glycans.
  • Cellular localizationSecreted. Neuroendocrine and endocrine secretory granules.
  • Information by UniProt
  • Database links
  • FormAccording to the Swiss-Prot database, this protein has many different forms which correspond to various molecular weights; thus the possible variation from the predicted molecular weight of 51kDa.

  • ICC/IF image of unpurified ab45179 stained PANC-1 cells. The cells were 100% methanol fixed (5 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 (ab45179, 1/50 dilution) 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.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human adenocarcinoma of pancreas tissue labelling Chromogranin A with purified ab45179 at 1/200. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9. ab97051, a HRP-conjugated goat anti-rabbit IgG (H+L) was used as the secondary antibody (1/500). Negative control using PBS instead of primary antibody. Counterstained with hematoxylin.

  • Unpurified ab45179 staining Chromogranin A in pig small intestine tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and blocked with 1% BSA for 10 minutes at 21°C; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/750 in blocking buffer) for 2 hours at 21°C. A Biotin-conjugated Goat anti-rabbit IgG polyclonal (1/250) was used as the secondary antibody.

  • Chromogranin A staining on monkey pancreas sections. The sections were subjected to heat mediated epitope retrieval using citric acid (pH 6) and blocked using 1% BSA for 10 mins at 21°C. Unpurifeid ab45179 was used at a dilution of 1/750 using TBS/BSA/Azide for 2 hours at 21°C. (Red arrowheads indicate extra Islet positive cells).
