Fig. 3. Quantification of relative mRNA abundance of branchial pFXYD. (A)
RT-PCR analysis confirmed the primer specificity. M, markers. (B) Comparison
between branchial mRNA abundance of freshwater (FW)- and seawater
(SW)-acclimated pufferfish, as quantified by real-time PCR. β-Actin was
used as an internal control. Values are means ± s.e.m. (N=6).
The asterisk indicates a significant difference between the FW and SW groups
(P<0.05, Student's t-test).
