isoform mRNA levels in Atlantic salmon acclimated to freshwater (control) or
to seawater (32
) for 30 days. mRNA levels are relative to that of the
control gene elongation factor 1
(EF1
) and normalized to the
Arctic char freshwater 30 day (control) group (normalized to a value of one).
*Significantly different (P<0.05) from both freshwater control
points; asignificantly different (P<0.05) from the 4
day seawater group. Sample size equals 8 for all groups.
