GeneChip Drosophila Tiling 2.0R Array
The Drosophila Tiling 2.0R Array builds on the content of its predecessor and includes additional sequences that have since become available through the Berkeley Drosophila Genome Project (BDGP).
The GeneChip® Drosophila Tiling 2.0R Array is Affymetrix' second-generation Drosophila Tiling Array. GeneChip Drosophila Tiling Arrays are versatile, whole-genome tools that researchers have successfully used to map novel areas of transcription and to interpret chromatin IP results on a genome-wide level.
The Drosophila Tiling 2.0R Array builds on the content of its predecessor and includes additional sequences that have since become available through the Berkeley Drosophila Genome Project (BDGP). The majority of the new sequences are located in the heterochromatin regions of the Drosophila genome.
- Up-to-date sequence content
- Based on BDGP genome release 5
- Release 5 improvements include heterochromatin regions, which contain several hundred known and predicted genes
- New design strategy enables a complete representation of the genome
- Includes repetitive regions
- No repeat masking used in chip design
- Novel tiling array design (see the Affymetrix White Paper, Drosophila Tiling 2.0R Array Design and Library files)
- 25-mer oligonucleotide probes interrogate the entire genome with an average 38-base-pair resolution
- Flexible analysis options
- Default analysis library file (bpmap file) excludes repetitive regions as defined by FlyBase 5.2 and UCSC Genome Browser repeat annotations
- Entire array content analysis library file available upon request through Customer Support
Note: Due to the different content, design strategy and analysis library file content, direct comparisons of results between the Drosophila Tiling 1.0R Array and the Drosophila Tiling 2.0R Array are not recommended.
