Neuromedin N is a neuropeptide derived from the same precursor polypeptide as neurotensin, and with similar but subtly distinct expression and effects.

4-Nitrophenyl dodecanoate (p-Nitrophenyl laurate) is a substrate for lipase and can be used to assess lipase activity.

Cecropin B (free acid) 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.
