GeneChipTiling Arrays are comprehensive tools available for discovery of novel RNA transcripts or mapping sites of protein/DNA interaction in chromatin immunoprecipitation experiments. The arrays feature 25-mer oligonucleotides for optimal hybridization specificity and offer users the ability to run experiments and refine protocols in their lab. Tiling arrays offer a physical readout of a genome and can be used as a discovery tool for mapping sites of protein/DNA interaction in chromatin immunoprecipitation (ChIP) experiments, discovering new RNA transcripts, or understanding global epigenomic changes like methylation or acetylation. GeneChip Tiling Arrays are designed using non-repetitive, Repeat Masked sequence content. Probes are selected at defined intervals throughout coding and non-coding sequences. All GeneChip Tiling Arrays feature 25-mer oligonucleotides. Base pair resolution describes the density of genomic coverage on arrays. Base pair resolution is measured from the central position of adjacent 25-mer oligos. Tiling arrays are designed based on the strandedness of the genome, rather than that of a particular transcript. Tiling arrays labeled with “R” are complementary to the reverse (-) strand of a genome and F arrays are complementary to the forward (+) direction.
