Scientific Data Images for Human Chromogranin B Antibody

Chromogranin B antibody in Human Pituitary Gland by Immunohistochemistry (IHC-P).

Chromogranin B in Human Pituitary Gland.

Chromogranin B was detected in immersion fixed paraffin-embedded sections of human pituitary gland using Mouse Anti-Human Chromogranin B Monoclonal Antibody (Catalog # MAB8868) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to epithelial cells.

Background: Chromogranin B

Chromogranin B (CHGB), also known as Secretogranin-1, is a 673 amino acid neuroendocrine secretory granule protein which is cleaved into three fragments: PE-11 (aa 575-585), GAWK peptide (aa 440-513) and CCB peptide (617-673). Human CHGB was originally isolated from human pheochromocytoma tissue, and is expressed in normal and malignant neuroendocrine tissues. CHGB peptides play a role in hormonal regulation in pancreatic islets, hypothalamus and pituitary gland. CHGB peptides, (aa 314-332 and 350-365) have been identified in several endocrine tumors including, gastrinoma, thyroid carcinoma, insulinoma, pancreatic endocrine tumor and pituitary adenomas.
