Expression levels of the epsilon class GSTs in two strains of A. gambiae. A Transcript copy number determined by qPCR using cDNA as a template. Results represent the average of three independent cDNA samples. B gene copy number, determined by using three independent aliquots of mass homogenates of gDNA as a template. In both cases, copy numbers were normalised against the copy number of the S7 genes and error bars represent standard deviations. Statistically significant differences (*p < 0.05, **p < 0.01) between ZAN/U and Kisumu are indicated. Kisumu is an insecticide susceptible strain, ZAN/U is resistant to DDT.
