Chromogranin A Antibody (Immunohistochemistry)

The Chromogranin A Antibody (Immunohistochemistry) is a highly specific immunohistochemical
marker used for identifying neuroendocrine tumors (NETs).
It serves as a precursor to several biologically active peptides, including vasostatin, pancreastatin, and parastatin,
which act as modulators in the neuroendocrine system.

Positive cytoplasmic staining for CgA is observed in neuroendocrine tumors of the lung, pancreas,
gastrointestinal tract, and adrenal glands, including pheochromocytomas and carcinoid tumors.

🔬 Features and Benefits Chromogranin A Antibody

• Highly specific marker for neuroendocrine differentiation

• Distinct cytoplasmic brown staining in positive cells

• Useful for differentiating neuroendocrine from non-neuroendocrine carcinomas

• Can be used with Synaptophysin and NSE for comprehensive diagnosis

• Excellent stability: 18-month shelf life at 2–8 °C

💡 Diagnostic Applications

• Detection of Neuroendocrine Tumors (NETs) in lung, pancreas, stomach, and intestine

• Identification of Pheochromocytoma, Paraganglioma, and Medullary Thyroid Carcinoma

• Differentiation of Carcinoid Tumors from other adenocarcinomas

• Research on neuroendocrine biology and tumor marker expression
