Figure 3.

Hook-characteristics of GeneChips of different generations (see figure, from left to the right). The chips are hybridized with mRNA extracts from tumour samples (thyroid nodules, two parts on the left; [9] and references cited therein) and from the Universal Human Reference RNA (chips c and d; see [10] for details). The figures show the raw hook (below), the corrected hook (middle), the probability density distribution (middle, right axis) and the theoretical curve fitted of the mix-, S- and sat-ranges of the corrected hook curves (above). The percentage of absent probes (%N) is given within the figures.
