From: Comparison of three different kits for extraction of high-quality RNA from frozen blood
Yield, purity, and integrity of RNA isolated from frozen blood using three different extraction kits. (A) The graph shows individual yields (n = 15). (B, C) The graphs show mean A260/A280 and A260/A230 ratios. Bars indicate standard deviations. (D) The graph depicts a box-and-whisker plot of variations in RIN values. The upper and lower edges of the boxes represent the 25% and 75% lines, and the central line shows median values. (E) RNA was run on a eukaryote total RNA Nano chip. 18S and 28S peaks of sample #2 are shown. ***p < 0.001 versus TRI reagent (b). ***p < 0.001 versus TRI reagent or PAXgene (C).
