This is amino acids 86 to 100 fragment of class II-associated invariant chain peptide called CLIP. The major histocompatibility complex class II molecule displays peptide fragments of foreign proteins to trigger a defensive reaction from the immune system. Before insertion of the foreign peptides into the binding groove, a place-holding peptide CLIP is removed. This is accomplished by the molecule DM, which is shown to increase the dissociation rate of a CLIP peptide from class II.

Adrenomedullin (13-52) is a 40 amino acid peptide with one intramolecular disulfide bridge, Adrenomedullin (13-52) is a high affinity ligand for the adrenomedullin receptor.

Substance P (1-7)(TFA) is a fragment of the neuropeptide, substance P (SP).
