Human Genome U133 Plus 2.0 Array

Affymetrix press release: Affymetrix Announces Commercial Launch of Single Array for Human Genome Expression Analysis, 2003-10-02

" The HG-U133 Plus 2.0 Array [...] combines the content of the previous HG-U133 two-array set with nearly 10,000 new probe sets representing about 6,500 new genes, for a total of nearly 50,000 RNA transcripts and variants. This new information, verified against the latest version of the publicly available genome map, provides researchers the most comprehensive and up-to-date genome-wide gene expression analysis. The probe design strategy of the HG-U133 Plus 2.0 Array is identical to the previous HG- U133 Set, providing very strong data concordance between the two products." [press release]
