High Performance Coated Slide for DNA Microarrays

Schott is has launched its latest generation of aminosilane microarray slides called Nexterion® Slide AStar. Aminosilane coated slides remain the most popular choice for printing cDNA, and oligonucleotides, despite the recent emergence of threedimensional microarray surfaces. The new aminosilane coating is the result of two years’ research at the Schott microarray R facility in Jena, Germany, and is available on a single standard slide, or in multi-well formats. Comparison studies with competitors’ products show that the Nexterion® Slide AStar surface produces the highest signal-to-background ratios.

Alistair Rees, Schott’s Microarray Product Manager, commented: “A significant number of users of DNA slides are still self printing onto aminosilane slides, despite a more general move to commercially printed DNA arrays. To better address their needs, we developed our new ‘high performance’ aminosilane coating to be fully compatible with standard slide processing protocols.” Schott offers free five-slide evaluation packs to those customers who wish to test the new slide coating.
