Specificity & Comments Supplied As Chromogranin A is present in neuroendocrine cells throughout the body, 200ug/ml of Ab Purified by Protein A/G. Prepared in 10mM PBS with 0.05% including the neuroendocrine cells of the large and small intestine, adrenal BSA & 0.05% azide. Also available WITHOUT BSA & azide at 1.0mg/ml. medulla and pancreatic islets. It is an excellent marker for carcinoid tumors, pheochromocytomas, paragangliomas, and other neuroendocrine tumors. Storage and Stability Co-expression of chromogranin A and neuron specific enolase (NSE) is common in neuroendocrine neoplasms. Reportedly, co-expression of Antibody with azide - store at 2 to 8°C. Antibody without azide - store at -20 certain keratins and chromogranin indicates neuroendocrine lineage. The to -80°C. Antibody is stable for 24 months. Non-hazardous. No MSDS presence of strong anti-chromogranin staining and absence of anti-keratin required. staining should raise the possibility of paraganglioma. The co-expression of chromogranin and NSE is typical of neuroendocrine neoplasms. Most Limitations pituitary adenomas and prolactinomas readily express chromogranin. This antibody is available for research use only and is not approved for use in diagnosis.
