Details
This peptide derived from the ligand binding site of the human γ-interferon (IFN-γ) receptor is an antagonist of human IFN-γ. It inhibited human IFN-γ-induced expression of HLR/DR antigen on Colo 205 cells with an approximate IC₅₀ of 35 µM. Immobilized peptide specifically bound recombinant human IFN-γ (H-1728). Tyrosine substitution at residue 121 allowed facile quantification and conjugation of the peptide.
