Enhanced Surface Treatments |
Tighter spot morphology without altering your chemistry...
In addition to the chemistries you require on a microarray slide (amines, epoxy, polylysine) Erie now offers the same attachment chemistries on a new, ES surface.
Arrayer spot-size is often controlled by the surface energy of the coating— hydrophobic coatings give smaller spot sizes, while hydrophilic coatings give larger spot sizes... But, a molecular biologist wants a specific coating on a mircroarray slide that will bind to the material they are spotting.
We have solved this problem by carefully controlling the surface morphology of the glass used in producing microarray substrates.
The result is a surface with microscopic canyons and valleys, but still uniformly coated with functional groups. The benefit to the researcher is that they can use the same attachment chemistries while obtaining smaller, more uniform spot size. Moreover, ES is microscopic—it will not affect the focusing or use of microarray spotters and scanners.
Erie’s new ES surface treatment produce a smaller, more uniform spot size without having to change your protocol.
