Lectins & Glycobiology Reagents

High-quality, purified lectins and other reagents for glycobiology and other applications

Lectins are a broad class of glycan binding proteins that have their origin as plant proteins known to agglutinate red blood cells. Since Lectins bind glycoconjugates in much the same way that antibodies bind antigens, researchers can use them to explore a myriad of biological structures and processes.

Specifically, Lectins can be used in glycobiology to:

  • Separate oligosaccharides, even those with identical sugar compositions
  • Discriminate between oligosaccharide structures
  • Isolate a specific glycoconjugate, cell, or virus from a mixture


Independent assessment of lectins by the National Center for Functional Glycomics (NCFG)

A selection of Vector Laboratories lectin products is independently assessed by the NCFG using the NCFG glycan arrays and the Consortium for Functional Glycomics (CFG) glycan arrays, providing researchers with detailed glycan-binding specificity. This data is available to the public on the NCFG website.

Lectin screening kits provide a panel of lectins or lectin conjugates selected to provide a variety of sugar binding preferences. The smaller volume unit sizes in these kits are of the same high quality as individually offered lectin units.

Anti-lectin antibodies are offered in unconjugated or in biotinylated formats. In some applications, using biotinylated anti-lectins in conjunction with unlabeled lectins may provide greater sensitivity than using biotinylated lectins alone.

All lectins manufactured by Vector Laboratories are extracted from a native plant source (i.e. seeds, bulbs, fruit etc.) and are not recombinant. Lectins are grouped based on their monsaccharide binding preferences.

While the eluting solutions are primarily used in lectin agarose column and slurry preparations, inhibiting sugars, when combined with lectin solutions, have appeal as negative controls to prevent binding in IHC, IF, ELISA and blotting applications.


The Lectins Application and Resource Guide is a content rich educational booklet that provides
insight into how lectins are applied in biological sciences. With a focus on plant derived lectins, the guide showcases the flexibility and utilization of lectins and lectin conjugates in established lab applications.
