ChipMap and RiboMap, GeneTac RA-1.


Ventana Medical Systems of Tucson, Ariz., has introduced two new chemistry kits for DNA microarray experiments on its Discovery automated slide-staining instrument. The kits, ChipMap and RiboMap, include reagents with optimized protocols that the company has designed to increase the efficiency of hybridization conditions. The kits minimize non-specific binding, and increase signal-to-noise ratios, the company said.

Genomic Solutions of Ann Arbor, Mich., has introduced the GeneTac RA-1, a benchtop high throughput microarrayer.

The company said the instrument, which has 48 solid titanium pins, could produce 25,000 to 50,000 spots per hour.

The unit includes an automated dynamic wash station that delivers and drains washing solution and air-dries the pins. The system also includes a fully enclosed array processing chamber, an onboard PC workstation with a 15-inch LCD monitor, and drop-down keyboard. The unit can accommodate both standard English and metric glass microscope slides.

The RA-1 “has higher specified arraying performance in a much smaller footprint and is about a third less costly than competitive microarrayers,” said George Hutchinson, Genomic Solutions product manger.
