Technical Data
C5069-96X
Chromogranin A, ID (CgA, CHGA, Parathyroid Secretory Protein 1, Pituitary Secretory Protein I, SP-I)
Description:
The protein encoded by this gene is a member of the chromogranin/secretogranin family of neuroendocrine secretory proteins. It is found in secretory vesicles of neurons and endocrine cells. This gene product is a precursor to three biologically active peptides; vasostatin, pancreastatin, and parastatin. These peptides act as autocrine or paracrine negative modulators of the neuroendocrine system. Other peptides, including chromostatin, beta-granin, WE-14 and GE-25, are also derived from the full-length protein. However, biological activities for these molecules have not been shown.

Applications:
Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.
