FIGURE 2

Effect of differing fixation times on quantification of epidermal growth factor receptor, p21, matrix metalloproteinase, and vascular endothelial growth factor mRNA species in oral tissues (n = 9). Solid bars indicate the mean change in relative expression for each marker in the same tissues fixed for differing intervals after normalization to the expression in unfixed, frozen tissue (0 h); no change = 1. Error bars represent standard deviations. All points were measured relative to β-N-acetyl-glucosaminidase.
