MetriGenix, Sequenom


MetriGenix of Gaithersburg, Md., last week announced the launch of its 4D Array System of chips and instrumentation.

The product is an oligo array system based on MetriGenix “flow-through” design system biochips, with hybridization and detection stations.

The 4D Array System options include: a proliferation array, a chip designed to characterize the expression profiles of genes in cell cycle regulation; an inflammation array: oligo probes for genes associated with inflammatory response; a lung cancer array designed to distinguish adenocarcinoma, squamous cell carcinoma and normal lung samples; a breast cancer chip: a chip designed to characterize expression profiles of genes involved in the diseas; and a neural degeneration array.

The company said it will design and produce custom arrays. The system can contain from 50 to 192 probes per array, packaged in a cartridge system offered in a kit with 10 arrays and reagents.


Sequenom will use Gentra Systems’ Puragene DNA purification kits in all its MassARRAY products, including the new Allelotyping line, Gentra said last week.

Puragene is a system for purifying DNA for applications including Southern blotting and PCR.

Gentra Systems, Inc., based in Minneapolis, Minn., specializes in developing nucleic acid purification reagents and instruments for clinical and clinical research labs.

The company markets its products globally through direct sales and distributors.
