Characteristics of FXIIa and IFNGR1 binder peptides. Sequences, dissociation constants (KD), inhibition constants (Ki), and half-lives in a serum stability assay are shown. “—” indicates that the KD value cannot be determined because the binding of F3A to FXIIa is too low or non-existent. 1: (1S,2S)-2-ACHC, 2: (1R,2R)-2-ACPC, 3:(1S,2S)-2-ACPC
