Small volumes of anti-CHGA antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

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. Two other peptides, catestatin and chromofungin, have antimicrobial activity and antifungal activity, respectively. Two transcript variants encoding different isoforms have been found for this gene.

CHGA: a member of the chromogranin/secretogranin family of neuroendocrine secretory proteins. It is found in secretory vesicles of neurons and endocrine cells and is a precursor to multiple biologically active peptides including vasostatin, pancreastatin, and chromostatin. Binds calcium with a low-affinity. Vasostatin negatively regulates angiogenesis and has antibacterial activity against some Gram-positive bacteria. Pancreastatin inhibits glucose induced insulin release from the pancreas. Chromostatin inhibits catecholamine release from chromaffin cells.
