Half-lives of Arg8 variant meditope–cetuximab interactions calculated using the formula t = ln(2)/kd. The off-rate of bimolecular interactions is independent of peptide/Fab concentration. All data were collected at 25°C in HBS-EP+ buffer pH 7.4. Unmodified, AHA-linked meditope with no modifications to Arg8; nBu, N-(n-butyl)arginine variant; nOc, N-(n-octyl)arginine variant; PrNH2, N-(3-aminopropyl)arginine variant; PrOH, N-(3-hydroxypropyl)arginine variant; EtCOOH, N-(carboxyethyl)arginine variant. |
