Chromogranin A (CgA, CHGA, Parathyroid Secretory Protein 1, Pituitary Secretory Protein I, SP-I)

Chromogranin A, a protein of 439aa which is encoded on chromosome 14, is present in neuroendocrine cells throughout the body, including the neuroendocrine cells of the large and small intestine, adrenal medulla and pancreatic islets. It 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.\n\nApplications:\nSuitable for use in ELISA and Western Blot. Other applications not tested.\n\nRecommended Dilution:\nELISA: 1:4000\nWestern Blot: 0.1-0.3ug/ml, observed in human kidney lysates on ~50kD bands\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months.
