Figure 2From: Comparison of three different kits for extraction of high-quality RNA from frozen bloodGraph of cycle thresholds (Ct) of three housekeeping genes assessed for RNA samples extracted using three different kits (TRI reagent, PAXgene, and NucleoSpin) and amplified using real time RT-PCR (n = 15). Bars indicate standard deviations. ***p < 0.001 versus TRI reagent.Back to article page
