(A) Plot of round four phage output on plates coated overnight with NT-3, BSA, or casein. (B) ELISA measurements of NLKEPYA, ADARYKS and SLTEPSS peptides or control Ph.D.™-7 peptide binding to NT-3 or casein (control). (C) Binding kinetics for NLKEPYA, ADARYKS and SLTEPSS peptides at 10, 100 and 200 μM concentrations to NT-3 proteins. kon, koff and KD are summarized in Table 5.
