Applied Biosystems said this week that it has introduced for its TaqMan gene expression assays more than 350,000 new pre-designed probe and primer sets. These are in addition to the current 40,000 off-the-shelf assays available for the platform.

“The new assays were designed over all viable exon junctions of transcripts associated with human, mouse, and rat genes, which may be especially important for researchers wanting to distinguish between biologically relevant splice variants of genes,” Andrew Last, vice president and general manager of Applied Biosystems gene expression, core PCR, and DNA synthesis, said in a statement. “Additionally, researchers conducting RNAi experiments now have a highly efficient and accurate method to confirm levels of gene knock-out or knock-down, including access to specific transcript locations needed for detection.”

SuperArray Bioscience said this week that it has launched the first two arrays in its new line of pathway-specific Oligo GEArray focused DNA microarrays.

These arrays include gene content specific to human hematology and human cancer, said the company.
