Figure 5From: Amplification biases: possible differences among deviating gene expressionsEvidence for gene expression differences between PCR and IVT amplified samples. Signal mean intensities per protocol were calculated on 24 arrays (4 arrays per target × 3 targets × 1 tissue = brain) and plotted pair-wise per protocol: PCR-amplified versus IVT-amplified using either the whole set of data (A) or its biological core (B). Coloured, the signals identified as significant gene expression differences between protocols whatever the tissues (n = 154; red: global PCR; blue: IVT one round).Back to article page
