CLIP (86-100) TFA is amino acids 86 to 100 fragment of class II-associated invariant chain peptide (CLIP). CLIP is a small self-peptide and cleavage product of the invariant chain that resides in the HLA-II antigen-binding groove.
CLIP (86-100) 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. CLIP (86-100) is accomplished by the molecule DM, which is shown to increase the dissociation rate of a CLIP peptide from class II.
