Figure 1From: Elasmobranch qPCR reference genes: a case study of hypoxia preconditioned epaulette sharksThe mRNA expression levels of the genes studied are represented by the raw Ct values. A) Cerebellum B) Heart C) Gills D) Eye. For each gene the three experimental conditions are displayed from left to right in three box-plots: control, single hypoxic insult and hypoxia preconditioning (8 hypoxic insults, 12 hours apart). The box indicates the 25/75 percentiles and the line marks the median.Back to article page
