Applied Biosystems, Biotage, ABI, MDS Sciex, Sequenom


Applied Biosystems this week launched Arabidopsis and Drosophila TaqMan Gene Expression Assays, the company said in a statement. The Real-time PCR assays are based on "well-characterized" transcripts in the US National Center for Biological Information Reference Sequence Project database, ABI said. The Arabidopsis assays include 95,000 probe-and-primer sets for approximately 26,000 genes, while the Drosophila assays include 38,000 sets for approximately 13,000 genes, the company said.

Biotage launched its first PyroMark cancer tests this week, the company said. The tests, based on Biotage's Pyrosequencing technology, identify mutations in the ras, MLH1, B-raf, and p16 genes, respectively, the company added. By analyzing DNA in 96 samples simultaneously, PyroMark is "significantly faster and more cost effective than traditional sequencing methods," Biotage said.

The 4800 MALDI TOF/TOF Analyzer mass spectrometer hit the market last week, said its makers, ABI and MDS Sciex, in a statement. The "most sensitive" mass spectrometer for identifying and quantifying protein biomarkers, it is "ten-fold" more sensitive than other commercially available systems, the companies said.

Sequenom's new iPLEX assay for fine-mapping and microarray validation launched last week, the firm said in a statement. The application, intended for Sequenom's MassArray, allows resolution "for as few as 10 to more than 1,500 SNPs," the company said. The product allows an average per-genotype cost of "less than 5 cents," multiplexing at the "level of 24," and throughput of "up to 100,000" genotypes per day.
