Cholecystokinin Octapeptide (1-2) (desulfated) (H-Asp-Tyr-OH) 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.
