Surface plasmon resonance experiments of 3d and erlotinib. (A) Binding sensorgrams for 3d interaction with immobilized wild-type of EGFR. The K_D(M) value between 3d and wild-type EGFR is 6.88 × 10⁻⁶. (B) Binding sensorgrams for 3d interaction with immobilized mutant protein of EGFR. The K_D(M) value between 3d and mutant protein EGFR is 3.12 × 10⁻⁶. (C) Binding sensorgrams for erlotinib interaction with immobilized wild-type of EGFR. The K_D(M) value between erlotinib and wild-type EGFR is 1.97 × 10⁻⁶.
