General description

Anti-Chromogranin-A antibody, Mouse monoclonal (mouse IgG1 isotype) is derived from the CHGA(419) hybridoma produced by the fusion of mouse myeloma cells and splenocytes from a BALB/c mouse immunized with synthetic peptide corresponding to the C-terminal region of human Chromogranin-A protein, conjugated to KLH. Chromogranin-A protein, also known as CgA, pituitary secretory protein I (SP-1) is the major member of the granin family of acidic secretory glycoproteins that are expressed in all endocrine and neuroendocrine cells. The protein is in neuroendocrine cells distributed throughout the body, including the neuroendocrine cells of the large and small intestine, adrenal medulla and pancreatic islets and the secretory vesicles of neurons.


synthetic peptide corresponding to the C-terminal region of human Chromogranin-A protein conjugated to KLH


Anti-Chromogranin-A antibody has been used in immunohistochemistry,immunoblotting.

Physical form

Biochem/physiol Actions

Chromogranin-A has a crucial intracellular role in secretory granule biogenesis and calcium homeostasis. Tissue-specific and context-specific proteolytic cleavage of Chromogranin-A yields polypeptides with paracrine and endocrine activity including: vasostatin, catestatin, GE25 and WE-14. Increased blood levels of Chromogranin-A have been shown in numerous inflammatory and non-inflammatory conditions, including neuroendocrine tumours (carcinoid tumors, phenochromocytomas, paragangliomas and others), renal failure, arterial hypertension, chronic heart failure and rheumatoid arthritis.
