D-Ala-Lys-AMCA hydrochloride, a known substrate of proton-coupled oligopeptide transporter 1 (PEPT1), emits blue fluorescence and may be transported into Caco-2 cells and liver cancer cells.

Intermedin (rat) 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.
