Figure 6From: Amplified RNA degradation in T7-amplification methods results in biased microarray hybridizationsSignal intensities from triplicate hybridizations with aRNA from 4 h and 16 h amplification. Shown is HGPRT (spot #12) which undergoes significant signal loss. All other signals are from neighbouring spots to eliminate HGPRT signal decrease due to some spatial property of the slides.Back to article page
