Combining the four different microarray platforms used in the CAMDA competition gives 2,449 genes in common. The platforms used were Affymetrix HG-U95 (Harvard, with 12,600 probe sets), Stanford spotted arrays (with 23,100 clones), Toronto OCI 19k2 spotted arrays (Ontario, with 19,200 clones), and Affymetrix HuGeneFL (Michigan, with 7,129 probe sets). See Table 1 for references.
