Figure 2. Summary of data from experiments that explore the cationic cluster.

A, HCO₃ ⁻‐dependent conductances (G _HCO3) computed between −20 and +20 mV of I−V relationships. G _HCO3 values were normalized to the G _HCO3 (dashed line) from an oocyte – studied the same day – expressing ∆9_40–48. The n for each group (i.e. construct) is 6. The asterisk over the straight bar indicates the six groups significantly different, by one‐way ANOVA followed by post hoc Tukey's comparison, from H₂O or B_WT oocytes. B, surface‐biotinylated proteins, analysed by western blotting. The 8 contiguous lanes (the H₂O is virtually blank) of the blot are aligned with the labels in A.
