Fosfomycin calcium is an antibiotics, used in urinary tract infections and intestinal infections caused by susceptible strains.

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.

TRH-AMC is a fluorogenic substrate used in a coupled assay for thyrotropin-releasing hormone(TRH)-degrading ectoenzyme.
