Corning and Promega Create Microarray Reagents Deal Targeting Home Brew Market


Corning this week announced a new microarray initiative in collaboration with Promega of Madison, Wis.

The two companies will develop and manufacture an integrated set of slides and reagents for the home-brew microarray market, which will be marketed as Pronto Plus Systems.

The strategic alliance follows the glass-slide maker’s entry into the microarray reagent market with a system for validation, printing, and hybridization. This system will be combined with Promega products including SV Total RNA Isolation, ChipShot labeling, and ChipShot cleanup.

A Market Re-entry?

The announcement is surprising given Corning’s history in microarray manufacturing. Citing market conditions in 2001, the company exited a one-year microarray venture, Corning Microarray Technologies, which was based on its cata-lytic converter technology, its Pyrex lab glass, and its flat panel display glass.

However, the company has continued to market its gamma-amino-propyl-silane (GAPS) coated glass slides for arrays, and maintain funding for a $10 million four-year research collaboration with MIT’s Whitehead Institute for Biomedical Research.

The companies are marketing the Pronto products in the following six kits:

Systems 1 and 2 ($545-$599) are for core facilities or printing groups wishing to validate Pronto Reagents from microarray manufacturing to hybridization; Systems 3 and 5 ($380-$435) are designed for researchers who will purify total RNA, generate labeled cDNA and hybridize to microarrays printed on Corning’s UltraGAPS slides; while Systems 4 and 6 ($950-$ 1,095) are configured for microarray researchers who obtain purified total RNA and need only to label cDNA and hybridize to DNA microarrays printed on UltraGAPS glass slides.
