Fig 1. Oligonucleotide versus cDNA microarrays. Oligonucleotide microarrays: direct synthesis or deposition of oligonucleotides onto solid surface and single-color readout of gene expression from a test sample. CDNA microarrays: deposition of polymerase chain reaction products from cDNA libraries onto a solid surface and simultaneous, two-color readout of gene expression in test and reference samples.
