Figure 2From: A universal reference sample derived from clone vector for improved detection of differential gene expressionSignal intensity (log2) of high (â–˛), medium (â– ) and low (â—Ź) mRNA abundances vs dilution. 1:25 dilution saturates high abundance RNA samples whereas 1:200 dilution results in undetectable signal for low abundance RNA. High, medium and low mRNA abundances. 1:50 dilution produces detectable but not saturated signal for the most spots.Back to article page
