Anti-CGA Antibody

This unconjugated rabbit polyclonal antibody from Antibodies.com targets Chromogranin A (CGA), an acidic glycoprotein stored within the secretory granules of neuroendocrine cells and co-released with catecholamines and peptide hormones during exocytosis. Produced in rabbit and supplied at 100 µl per vial, the reagent is validated for western blot, immunohistochemistry, and immunofluorescence workflows on human samples, supporting detection of CGA in fixed tissue sections, cultured cell preparations, and denatured protein lysates.

CGA is widely used in research as a broad marker of neuroendocrine differentiation, with established applications in studies of pheochromocytoma, carcinoid tumors, pancreatic islet cell neoplasms, and small intestinal neuroendocrine lesions. Polyclonal anti-CGA reagents are favored when researchers need to detect multiple epitopes across the chromogranin A precursor and its partially processed fragments, including pancreastatin, vasostatin, and parastatin. The unconjugated format allows flexible downstream labeling with HRP-conjugated, biotinylated, or fluorophore-conjugated secondary antibodies suited to each assay platform.

Store the vial refrigerated upon arrival; for extended storage, aliquot and freeze to minimize freeze-thaw cycles and preserve antibody activity. Provided by Antibodies.com for research use only, in vitro laboratory applications.
