Abstract

Lectin microarray technology has been used to profile the glycosylation of a multitude of biological and clinical samples, leading to new clinical biomarkers and advances in glycobiology. Lectin microarrays, which include >90 plant lectins, recombinant lectins, and selected antibodies, are used to profile N-linked, O-linked, and glycolipid glycans. The specificity and depth of glycan profiling depends upon the carbohydrate-binding proteins arrayed. The current set targets mammalian carbohydrates including fucose, high mannose, branched and complex N-linked, α- and β-galactose and GalNAc, α-2,3- and α-2,6-sialic acid, LacNAc, and Lewis X epitopes. Previous protocols have described the use of a contact microarray printer for lectin microarray production. Here, an updated protocol that uses a non-contact, piezoelectric printer, which leads to increased lectin activity on the array, is presented. Optimization of print and sample hybridization conditions and methods of analysis are discussed.
