Fig. 4From: Identification of undecylenic acid as EAG channel inhibitor using surface plasmon resonance-based screen of KCNH channelsDetermination of the binding affinity of undecylenic acid for the mEAG PAS domain. Plots of the SPR response at 55 s after the start of the injection versus total undecylenic acid concentration for sensorgrams shown in Fig. 3b. The lines represents fit of the data with Hill equation. The binding affinity for undecylenic acid was ~ 11 μMBack to article page
