CHGA antibody has been tested by ELISA, Western blot and immunohistochemistry analysis to assure specificity and reactivity. Recommended dilution range for Western blot is 1:500 ~ 1:1,000 and immunohistochemistry analysis is 1:100~200. Recommended starti
Anti-human CHGA mAb is derived from hybridization of mouse F0 myeloma cells with spleen cells from BALB/c mice immunized with recombinant human CHGA amino acids 19-131 purified from E. coli.
Chromgranin-A is part of the neuroendocrine secretory protein family. CHGA is located in secretory vesicles of neurons and endocrine cells. Chromgranin-A 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. Chromgranin-A has numerous biological activities on some tissues and organs and exerts a large spectrum of homeostatic actions, including antifungal and antimicrobial effect, modulation of cell adhesion, and inhibition of parathyroid hormone secretion.
