  The GeneChip Human Genome U133A 2.0 Array is a single array representing 14,500 well-characterized human genes that can be used to explore human biology and disease processes.
  Provides coverage of well-substantiated genes in the transcribed human genome on a single array
  Analyzes the expression level of 18,400 transcripts and variants, including 14,500 well-characterized human genes
  Comprised of more than 22,000 probe sets and 500,000 distinct oligonucleotide features
  All probe sets represented on the GeneChip Human Genome U133A Array are identically replicated on the GeneChip Human Genome U133A 2.0 Array
  Sequences used in the design of the array were selected from GenBank®, dbEST, and RefSeq. The sequence clusters were created from the UniGene database (Build 133, April 20, 2001) and then were refined by analysis and comparison with a number of other publicly available databases including the Washington University EST trace repository and the University of California, Santa Cruz Golden-Path human genome database (April 2001 release).
