Figure 3From: Impact of sample acquisition and linear amplification on gene expression profiling of lung adenocarcinoma: laser capture micro-dissection cell-sampling versus bulk tissue-sampling Density plot of probeset distance to gene 3' end, for probesets with observed amplification bias (solid line) and a control set of all highly expressed (≥ log 2 8) probesets (dashed line). The biased probesets have a statistically different density distribution, shifted to the right, further from the gene's 3' end.Back to article page
