More uniform spot morphology without altering your chemistry or buffers...

In addition to the chemistries you require on a microarray slide (amines, epoxy, polylysine, protein surfaces) Thermo Fisher Scientific offers the same attachment chemistries on an 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...and the buffers used.

We have developed a surface that will provide a larger binding capacity without altering the buffer or coating you need. 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 a more uniform spot size.

Moreover, the ES modification is microscopic—it will not affect the use of microarray spotters focusing of scanners.
