Affymetrix is accepting orders and is shipping its HG-U133 Plus 2.0 Array, the single-chip microarray product containing 1.3 million probes for 50,000 RNA transcripts for the human genome, according to a company spokesman. An article published in the Dec. 31 edition of BioArrray News erred in reporting that the product, launched Oct. 2, was in limited release. BioArray News regrets the error.
