Chromogranin A is a soluble protein that is stored and released with catecholamines from their secretory vesicles. Its measurement is a probe of exocytotic sympathoadrenal activity, and in plasma it may also be a useful tool in the diagnosis of peptide producing endocrine neoplasms. Because we have found that chromogranin A is elevated in ...Chromogranin A (CHGA) was identified as a major soluble protein in adrenal medullary chromaffin granules almost 4 decades ago ().Since then it has been found to be a ubiquitous protein stored in dense-core secretory granules of the endocrine, exocrine, and nervous systems, along with their respective hormones, enzymes, and neuropeptides and neurotransmitters.The rapid identification of group A beta-hemolytic streptococci in the upper respiratory tract.
