Figure 7. Summary of pHi recovery rates (dpHi/dt) of oocytes expressing different mouse NBCn1 variants.
Mouse NBCn1 variants are tagged with EGFP at the Nt. Oocytes expressing mouse NBCn1 were superfused using a protocol like that shown in Fig. 5. The data set for H2O-injected control oocytes is independent of that summarized in Fig. 6. A one-way ANOVA shows that the omnibus overall P value is 4.5 × 10−11, indicating statistically significant differences among different variants and H2O. Moreover, a post hoc Tukey's analysis following the ANOVA shows that NBCn1-E and -F are significantly different from the other NBCn1 variants, but not H2O. The insignificance of NBCn1-E and -F vs. H2O-injected oocytes is simply a result of the small sample size and lack of power. An asterisk indicates the groups significantly different by one-way ANOVA followed by post hoc Tukey's comparison. Numbers in parenthesis: N of oocytes.
