Chromogranin-A(CHGA) is a member of the granin family of system body fluid proteins, its situated in body fluid vesicles of neurons and endocrine cells. In humans, chromogranin-A supermolecule is encoded by the CHGA factor. Chromogranin A is a 68 kD acidic protein which is reported to be widely expressed in neural tissues and in secretory granules of human endocrine cells eg parathyroid gland, adrenal medulla, anterior pituitary gland, islet cells of the pancreas and C cells of the thyroid. cdsbucykdvbsuck
Chromogranin-A is that the precursor to many practical peptides together with vasostatin, pancreastatin, catestatin and parastatin. These peptides negatively modulate the system operate of the cathartic cell or close cells. Different peptides derived from chromogranin-A with unsure operate embody chromostatin.
The Chromogranin-A test is in situdy of 5-HIAA to assist diagnose tumor. Its conjointly accustomed facilitate monitor the effectiveness of treatment and sight return of this tumour. Generally its ordered with specific hormones, like catecholamines, to assist diagnose and monitor a tumour. Its accustomed sight the presence of different system tumors, even people who dont secrete hormones. we often use a chromogranin-A crp elisa kit for this test.
