Fig. 7. — Charge selectivity of junctions formed by cells coexpressing Cx43 and Cx40 at different expression ratios. A: plot of B_NBD-M-TMA vs. B_{Alexa 350} for A7r5C3 () and A7r5 (•) cell junctions (dotted lines are the linear regression fits for Cx40 and Cx43 junctions as shown in Fig. 2A). Inset shows data near graph origin at expanded scaling of both axes. B: the average charge selectivities (B_NBD-M-TMA/B_{Alexa 350}) of A7r5 and A7r5-C3 junctions are significantly different, P < <0.001. *Selectivity of A7r5-C3 junctions significantly greater than A7r5 junctions (Student's t-test).
