Figure 1From: Significance analysis of microarray transcript levels in time series experimentsExperiment outline. The case study provides a typical example of experimental design in time series gene expression studies. Samples are collected from an insulin treated and a control culture. The expression level measured in treated and control culture for a single probe-set (corresponding to "Early growth response 1" gene) is shown in the lower part of the Figure. The area A bounded by the two expression profiles T and C is coloured in gray.Back to article page
