Figure 4From: Quantification of mRNA in single cells and modelling of RT-qPCR induced noiseHistogram showing expression levels of three genes ( Rps29, Chgb and Ins2 ) in 101 β-cells. Overlaid curves show the total technical noise levels for RT-qPCR measurements. The biological noise, which can be interpreted as normalized width of each histogram, is 1.0, 0.33 and 1.4 for Rps29, Chgb and Ins2 respectively.Back to article page
