Galanthus nivalis (snowdrop) lectin (GNL), Unconjugated

Galanthus Nivalis Lectin (GNL), Unconjugated, 5 mg. GNL, unlike most mannose-specific lectins, is not a metalloprotein and does not require Ca++ or Mn++ for binding. Binding seems to be preferentially directed toward structures containing (alpha-1,3) mannose residues. Also, in contrast to most mannose-binding lectins, GNL will not bind alpha-linked glucose. Reports indicate that this lectin binds rat and mouse IgM but not IgG. The only protein from human serum reported to bind to this lectin is alpha2-macroglobulin. GNL binds to many viral glycoproteins.
