Affymetrix press release: ??? (2008?)
Affymetrix product page: "Measure gene expression of more than 47,000 transcripts and variants, including more than 33,000 well-characterized genes and UniGene clusters per sample." [...] "Two design changes were introduced with the GeneChip HT HG-U133+ PM Array Plate: (1) Only perfect match (PM) probes from the cartridge design were retained while mismatch (MM) probes were removed. (2) Empirical data was used to select the best-performing probes resulting in reducing the number of PM probes; (i) 42,461 probe sets were reduced from 11 to nine probes (ii) Six probe sets were reduced from 11 to 10."
