Ready-to-use ELISA kits are available for the detection of Pancreastatin, an alias of the protein, chromogranin A. The official gene symbol is CHGA. The kits can detect several species variants of the protein, including: human, mouse, rat, bovine, chicken, primate, guinea pig, and other mammalian. The protein, with a mass of 50.7 kDa and length of 457 residues, is reported to be secreted. It is a member of the Chromogranin/secretogranin protein family and may be known by other names, including: pituitary secretory protein I, chromofungin, catestatin, betagranin (N-terminal fragment of chromogranin A), and SP-I.
