Microarray Slides for glycan (carbohydrate) applications

Glycan microarrays are presentations of multiple glycans or glycoconjugates printed on a slide for screening with glycan-binding proteins, e.g. lectins, antibodies, bacteria, and viruses.

All of PolyAn’s reactive surfaces are completely transparent. They are characterised by a low lot-to-lot variation that is specified and monitored by using contact angle measurements as well as qualitative test methods.

Glycans are usually derivatized with functional groups and can be immobilzed for example on PolyAn's 2D-Epoxy, 3D-Epoxy and 3D-NHS functionalized glass slides or onto PolyAn's functionalized 96-well plates.

A flyer showing the most commonly used functionalized surfaces for Glycan Microarrays available from PolyAn can be downloaded here.

More hydrophobic surfaces may result in reduced spot diameter, depending on the spotting buffer composition. Results may vary based on buffers, sample preparation, spotting and scanning instruments.

Please note, that in order to facilitate handling of the glass slides PolyAn also offers a range of useful accessories and reagents.
