PYR-GLY-PRO-TRP-LEU-GLU-GLU-GLU-GLU-GLU-ALA-TYR(SO3H)-GLY-TRP-MET-ASP-PHE-NH2

Gastrin I (human) (sulfated) is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development[1].
