Chip RNA quality versus some pre-mortem and post-mortem attributes. Median of beta actin ratios in a sample set related to the same donor versus donor pre-mortem and post-mortem attributes. Each point represents a single donor. Each sample set contains samples derived from various brain areas of one donor. Donors (x-axis labels) are ordered by corresponding parameter, 5 point moving average trend lines are shown. A barely perceptible decrease in trend line is present with decreasing brain pH (r = 0.26), but only for HG-U133_Plus_2.0 chip data.
