  The GeneChip® Human Tiling 2.0R Array Set is designed for chromatin immunoprecipitation (ChIP) experiments. This set of seven arrays contains approximately 45 million oligonucleotide probes to interrogate the human genome. Each array in the set contains over 6.5 million perfect match probes to specifically interrogate genomic regions.
  Sequences used in the design of the Human Tiling 2.0R Array Set were selected from NCBI human genome assembly (Build 34). Repetitive elements were removed by RepeatMasker. The Human Tiling 2.0R Array Set is available either as a whole-genome set of seven arrays (P/N 900772), or individual arrays from the set may be purchased separately. The GeneChip® Human Promoter 1.0R Array is a subset of the Human Tiling 2.0R Tiling Array Set, and the content was chosen specifically to analyze protein/DNA interactions within promoter regions.
  Probes are tiled at an average resolution of 35 base pair, as measured from the central position of adjacent 25-mer oligos, leaving a gap of approximately 10bp between probes. Oligonucleotide probes are synthesized in situ complementary to each corresponding sequence.
