BD Biosciences Clontech, Corning


BD Biosciences Clontech has introduced the Ab Array 500 microarray. The glass slide array, which succeeds a chip with 380 antibodies, enables users to fluorescently detect proteins for signal transduction, cell-cycle regulation, gene transcription, and apoptosis. Acording to BD Clontech, detection of as little as 20 pg/ml of each protein target is possible.


Corning has introduced a new line of microarray reagents. The Pronto cDNA and Universal Microarray Reagent System is offered as a complete microarray suite of products, optimized for use with Corning’s UltraGaps slides, for printing through hybridization, the company said.

The product package includes a new spotting solution with a sensitivity of 0.5 pg per 5µg of input Total RNA, or one to two copies per 500,000 cells. The systems are comprised of kits for system validation, printing, and hybridization.
