Monoclonal Mouse Affinity Purified IH
Chromogranin A (CgA) is a secretory glycoprotein and member of the chromogranin/secretogranin family It is widely expressed by cells of the neuroendocrine system and related tumors, which is used in immunohistochemistry as a valuable diagnostic marker for pheochromocytomas, paragangliomas and carcinoid, pancreatic and prostate tumors. CgA constitutes one of the most abundant components of secretory granules, and is the precursor to several functional peptides including vasostatin and pancreastatin.
