Figure 4From: Selection of housekeeping genes for gene expression studies in larvae from flatfish using real-time PCRTranscriptional levels (Ct values) of candidate reference genes (GST, 18S rRNA, RPL13a, RPS4, ODC) during larval development. Age is indicated as days after hatching (lower, Senegalese sole; upper, for Atlantic halibut). Metamorphosis period is shaded.Back to article page
