Figure 5.

Distribution of log₁₀ ratio differences between conditions for all four tumors. Distributions of log₁₀ ratio differences for the 182 of the 232 genes that had signals significantly above background (signals > 15) are plotted. Each set of log₁₀ ratios were compared with another set by subtracting the log₁₀ ratios of one set from those of the other to get a set of 182 log₁₀ ratio differences. The green distributions compare arrays with the same labeled sample, hybridized in different laboratories. The blue distributions compare arrays labeled at different locations but hybridized at the same location. The black distributions compare arrays with different labeled samples, hybridized in different locations. Each curve is a probability distribution (normalized histogram) of the differences between the average log₁₀ ratios of the 182 probes in one condition, and their average in the other condition.
