GP(33-41), a 9-aa-long peptide, is the optimal sequence of the GP1 epitope of lymphocytic choriomeningitis virus and can upregulate H-2Db molecules at the RMA-S (Db Kb) cell surface with an SC50 of 344 nM. GP33-41 Epitope is a strong agonist of CD8 T cells.
GP531 is a second-generation adenosine regulating agent. It is pharmacologically silent under basal conditions but increases localized endogenous adenosine during ischemia.
Gp100 (25-33) corresponds to residues 25 to 33 of the mouse self tumor antigen glycoprotein (mgp100), which is an enzyme responsible for pigment synthesis. This epitope fragment is found in both normal melanocytes and melanoma cells.
