Abstract Affymetrix has created a new generation of expression chips, based on placing probes across the entire length of a transcript. This includes the Exon arrays and the newer Gene arrays. In this talk, I will discuss a performance comparison of gene-level expression summaries using publicly available data from a tissue experiment and a designed mixture experiment. We make comparisons of the 3 platforms in terms of the coverage of expressed content, reproducibility and detection rates.
