Fig. 5. Expression of neuroglobin (Ngb) in zebrafish eye and brain, and myoglobin
(Mb) in heart. Zebrafish were kept for 48 h at normoxia (white columns) or
PO2=
4.1 kPa (black columns). Ngb protein levels from
eye and brain, and Mb levels from heart, were quantified separately (100 µg
protein per lane; N=3). The units of the y-axis are
arbitrary. ***P<0.001; *P<0.05
(t-test).
