Figure 2From: Microarray amplification bias: loss of 30% differentially expressed genes due to long probe – poly(A)-tail distancesAgarose gel electrophoresis of amplified RNA samples. The average sizes of the aRNA of the duplicate tumor samples (T1 and T2) and the bronchus sample (B) is more reduced after two rounds (2x) as compared to the average aRNA sizes after one round (1x) of amplification.Back to article page
