Applied Biosystems last week announced the expansion of its TaqMan Gene Expression Assays product line for real-time PCR. The company announced the availability of 350,000 new probe and primer sets for RT-PCR analysis of human, mouse, and rat genes. The Taqman assays are available for nearly all exon-exon junctions of human, mouse, and rat gene transcripts and are designed for use on Applied Biosystems’ RT-PCR systems including the Expression Array System, and the TaqMan low-density array products, as well as the Celera Discovery System.
