KCNQ1/KCNE1 - block by Chromanol 293B

  Patchliner data and applications: 
Data kindly provided by ApconiX, UK

KCNQ1/KCNE1 expressed in CHO cells was activated using a 2 s voltage step to 40 mV and blocked by increasing concentrations of chromanol 293B.  Shown are traces from an example cell in the absence and presence of chromanol 293B and the normalized concentration response curve for an average of 6 cells. The curve was fit with a Hill equation revealing an IC₅₀ = 2.8 ± 0.9 μM (n = 6).
