Fig. 4. Expression profiles for IGFBPs 2–6 and IGFBP-related protein 1 (IGFBP-rP1) in fast muscle of Atlantic salmon from fish with zero growth rate (0 days) that were then fed to satiation at days 3, 5, 7, 14, 30 and 60. Gene expression was normalised to the geometric average of three reference genes (Genorm analysis); see text for details. Values represent means ± s.e.m., 10 fish per sample point. Significant differences between means are indicated by different letters.
