Figure 2. Surface plasmon resonance (SPR) analysis of PKAc–phospholamban (PLN)/ALN interactions.

(A–K) SPR sensorgrams of the binding of the PLN/ALN peptides onto immobilized PKAc. The calculated KD values are displayed above the corresponding sensorgrams. (L) The relative KD values of PKAc with different peptide substrates measured by SPR assay.
