Figure 4From: Housekeeping while brain's storming Validation of normalizing factors for gene expression studies in a murine model of traumatic brain injury95% Confidence intervals for equivalence between experimental groups. TG/TG' corresponds to the interval calculated between group G and group G'. With T0: control group and T1, T2, T3, T4, T5 and T6 trauma groups sacrificed at 30 min, 3 h, 6 h, 12 h, 24 h and 48 h respectively. For symmetrical reasons, since Iij = Iji, only (Ii,j)i≤j are plotted. For each of the normalization factor: If 0 ∉ I ij , its level is significantly different between experimental conditions i and j. If I ij ⊂ [-ε; ε], its level is equivalent between experimental conditions i and j. A: Oligreen measurements; B: 18S rRNA; C: S100β; D: GAPDH; E: β-actin; F: β-microtubulin.Back to article page
