This antibody does not react with Rat.
Immunohistochemistry (PFA fixed): incubate antibody for 30 min RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95 degrees C followed by cooling at RT for 20 minutes.
Chromogranin A (CHGA) is a member of the chromogranin/secretogranin family of neuroendocrine secretory proteins. It is found in secretory vesicles of neurons and endocine cells. CHGA is a precursor to three biologically active peptides: vasostatin, pancreastatin, and parastatin. These peptides act as autocine or paracrine negative modulators of the neuroendocrine system. CHGA is an excellent marker for carcinoid tumors, pheo-chromocytomas, paragangliomas, and other neuro-endocrine tumors. Coexpression of chromogranin A and neuron specific enolase (NSE) is common in neuroendocrine neoplasms.
