The G280-9 peptide, a common melanoma gp100 epitope restricted by MHC-associated HLA-A2. The G280-9 sequence is unique because it could be recognized by cytotoxic T lymphocytes at very low concentrations, however it shows low total immunogenicity that may be attributable to relatively low affinity of this peptide for the HLA-A2.

TNF-α (10-36), human is a potent pro-inflammatory cytokine involved in the acute phase stress response.
