H-Leu-His-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[1].
ChEBI: Leu-His is a dipeptide formed from L-leucine and L-histidine residues. It has a role as a metabolite.
