Figure 4From: Selection of housekeeping genes for gene expression studies in the adult rat submandibular gland under normal, inflamed, atrophic and regenerative statesCandidate housekeeping gene expression normalised to total RNA and relative to the normal state. In the figure n = 5 per experimental group and error bar represent ± SD. The Mann Whitney-U test was used to test for differences between sample sets. UBC and SDHA were the only two genes which showed no significant difference (>0.05) throughout the different groups when compared with the control group.Back to article page
