Chromogranin A / CHGA (Neuroendocrine Marker)

Product Overview

Chromogranin A (CHGA) (Neuroendocrine Marker); Clone CHGA/1773R (Concentrate) is a recombinant monoclonal antibody designed to specifically detect Chromogranin A, a key acidic glycoprotein found within the secretory granules of neuroendocrine cells. Clone CHGA/1773R provides strong, consistent cytoplasmic staining in formalin-fixed, paraffin-embedded (FFPE) tissue sections, making it a highly reliable tool for immunohistochemical identification of neuroendocrine differentiation. Chromogranin A is widely used in diagnostic pathology to identify neuroendocrine tumors such as carcinoids, pheochromocytomas, pancreatic neuroendocrine tumors, and small cell carcinomas. The recombinant nature of this clone ensures high lot-to-lot consistency, improved specificity, and reduced background staining. Its concentrated format allows for flexible dilution and protocol customization. Clone CHGA/1773R is a robust and essential reagent for pathologists and researchers working in the fields of oncology and neuroendocrine tumor diagnostics.
