New England Biolabs (NEB) offers a selection of products for glycobiology research:
Many of these reagents are recombinant, and all undergo several quality control assays, enabling us to provide products with lower unit cost, high purity, and reduced lot-to-lot variation. All our glycosidases are tested for contaminants. Since p-nitrophenyl-glycosides are not hydrolyzed by some exoglycosidases, we use only fluorescently-labeled oligosaccharides to screen for contaminating glycosidases.
We don't have any products in this category online at this moment. Please contact firstname.lastname@example.org for inquiries.
