MI Dog Ready Array for study of Canis familiaris contains 25,383 probes long oligo probes. The design parameters targeted probe placement to be fully contained within a single exon, making this probe set also applicable for CGH (comparative genome hybridization) experiments. These MI Dog Ready Array probes are able to detect alternative splice variants from Ensembl C. familiaris release 44.2b genebuild which is based on from the CanFam 2.0 whole genome shotgun assembly (May 2006) provided by the Broad Institute. CanFam 2.0 genebuild predicts 27,310 gene transcripts and 1,926 RNA genes. In this probe set, 27,039 transcripts are covered by at least one oligo probe providing essentially full coverage of the canine nuclear and mitochondrial genomes.
