WebChromogranin B. Chromogranin B (657 amino acid peptide) (CgB) or GAWK (a partial sequence of CgB 420–493) coexists with CgA in the secretory granules and bears a strong homology to CgA in the terminal regions. CgB is also known as secretogranin I and secretoneurin. Like CgA, it is an acidic protein (Benedum et al., 1987 ). WebTypically, chromogranin A levels are around 2.5 times higher with the LC/MS/MS assay—this relationship is captured by the following equation: ELISA result = 13.6 + 0.36 × LC/MS/MS result; correlation coefficient = 0.71.
