Orientation of GST-tagged lectins via in situ surface modification to create an expanded lectin microarray for glycomic analysis

Mol Biosyst. 2011 Jul;7(7):2114-7. doi: 10.1039/c1mb05047h. Epub 2011 May 20.

Abstract

Herein we describe the orientation of GST-tagged lectins on NHS-activated slides via a one-step deposition of the protein and a glutathione (GSH) scaffold. This technology overcomes the need for a premade GSH-surface to orient GST-tagged proteins, enabling us to rapidly expand the analytical capacity of lectin microarrays through addition of oriented lectins, while maintaining lectin diversity.
