Figure 1From: Suitability of endogenous reference genes for gene expression studies with human intraocular endothelial cellsThe distribution of gene expression levels of candidate reference genes in hCEC (A) and hREC (B). Values are given as qRT-PCR Ct values. The boxes represent the 25 to 75 percentile ranges with medians (line in the box); the whiskers illustrate the 1 to 99 percentile of the samples.Back to article page
