Abstract :
[en] Gastrin, secreted by G cells, plays a crucial role in digestion and has diverse functions including regulation of the intestinal epithelium and stomach growth. Gastrin peptides are derived from progastrin. Peptides G17 and G34 are the most abundant in the blood. Both of them may be sulfated. Current gastrin measurement relies on the DIAsource RIA kit, however it displays cross-reactivity issues. Therefore, we developed a LC-MS/MS method to quantify both sulfated and non-sulfated G17 and G34 forms.
