Figure 7

Peptide block rate and IK1 activation. Inset: Sample, whole-cell current records in response to a voltage pulse to 50 mV from an experiment with 250 μM of the IK1 N-terminal peptide in the patch pipette. Data are shown before (Control), during (DCEBIO), after (Washout) application of 10 μM DCEBIO. The red lines are the results of single exponential time function fits to the data with the indicated time constant values. Calib: 0.2 nA/pF, 100 msec. Main: The peptide block rate (1/τ) as a function of the IK1 level during washout of DCEBIO. The dashed line is a linear fit to the data.
