CodeLinkā¢ Rat Whole Genome Bioarray is designed to interrogate approximately 34,000 transcripts representing most of the known and predictive genes of the rat genome, as it is described today in the public domain. Each transcript is represented by a 30-mer probe which is designed to conserved exons across the transcripts of targeted genes. The probe sequences, representing well-annotated, full-length and partial rat gene sequences, were designed based on sequences selected from the NCBI UniGene build #129, RefSeq database (April 1, 2004 release) and dbEST database (March 20, 2004 release). Well-annotated mRNA or coding sequences were chosen to ensure usefulness for a large range of applications in basic research, biotechnology, and drug development. Each sequence was carefully screened to ensure high-quality, specific probe design, and to reduce redundancy of gene targets. All of the probes designed to these sequences were functionally tested, and over 95% were functionally validated against 10 rat tissues to ensure best representation of the gene and biologically relevant results.
The genes represented by CODELINK probe sets were annotated using the biocLite package (BioConductor) with the library "rwgcod.db" for CodeLink Rat Whole Genome arrays.
