SANTA CLARA, Calif.--Affymetrix has introduced a family of GeneChip expression arrays for the rat, and separately, its GeneChip HuSNP mapping assay, an integrated tool for generating genotypes needed for genetic linkage mapping. Central to the assay is a new GeneChip HuSNP probe array, containing oligonucleotides of known sequences enabling simultaneous interrogation of nearly 1500 single nucleotide polymorphisms covering all 22 autosomes and the X chromosome in a single experiment.
The new rat arrays, including the Rat Genome U34 and the Rat Toxicology U34 array, along with advanced assay protocols, are designed to measure expression levels in thousands of rat genes and expressed sequence tags. Affymetrix is introducing simultaneously the companion GeneChip Test2 array for RNA sample quality verification.
The company also announced the promotion of Susan Siegel to president from her post as senior vice president of marketing and sales which she has held since last year. Stephen Fodor remains CEO and has become chairman while John Diekman, the former chairman, is now vice-chairman.
