Fig. 2. The estimated absolute expression levels of several genes important for ion
transport in the gills (black bars) and opercular epithelium (grey bars) of
killifish (N=1520). Values are determined using Formula 1 and
data are normalized to the expression level of elongation factor 1
(EF1
). Na+,H+-exchanger 2 (NHE2) was not
amplified above background levels in opercular epithelium. NKA,
Na+,K+-ATPase
1a; VHA, V-type
H+-ATPase A. #Significant difference between tissues
(P<0.05).
