Fig. 4

(A) Confocal images of native KCNQ1 and KCNE1 detected as Alexa488 ‘green’ and Alexa568 ‘red’, respectively. (B) Box plot of degree of KCNQ1/KCNE1 overlap in cell periphery, quantified by Pearson correlation coefficients of immunofluorescence signals that were above threshold (pixels in cell free areas). Numbers of myocytes analyzed are shown in parentheses; * t-test, Ang ll vs Veh, p < 0.05.
