All amino acid residues in the original sequence are required for A5G81 bioactivity. (A) HDF and HEKa were cultured on SAMs presenting a peptide (1 mol%) against a background of tri(ethylene glycol). Monolayers were prepared by immobilizing cysteine-terminated peptides onto maleimide-terminated dioctadecyl disulfide. (B) Adhesion of HDF and HEKa on SAMs presenting truncated versions of A5G81. (C) Adhesion of HDF and HEKa on SAMs presenting alanine-substituted versions of A5G81 (n = 3; all data are presented as mean ± SD).
