Gp100 (25-33), human TFA is a 25-33 amino acid fragment of human melanoma antigen.Gp100 (25-33), human TFA is a 9-amino acid (AA) epitopes restricted by h-2db and recognized by T cells.

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.

Dehydropipernonaline is a useful organic compound for research related to life sciences.
