Surface plasmon resonance analysis of the fibrillin-1 PF3 construct binding to LTBP4. (A) CWT, (B) C1286S, and (C) C1186R. LTBP4 was immobilised on the sensor chip (GLC) using amine coupling and purified fibrillin-1 (PF3) was injected as analyte at different concentrations (100–3.1 nm) over the immobilised LTBP4. The binding affinity was determined by steady state with equilibrium response plotted against fibrillin-1 concentration as shown in panel (ii) for all constructs. All experiments were performed in at least duplicate and representative curves shown.
