Galanthus nivalis lectin (GNA) (1 gram)
For Research Use Only
Galanthus nivalis lectin is isolated from snowdrop bulbs and has a molecular weight of 52 kDa. The lectin contains little or no carbohydrate and does not need Ca2+ or Mn2+ for binding, since unlike most mannose-specific lectins it is not a metalloprotein. Structures containing (α-1,3) mannose residues are preferred for binding. Unlike the majority of mannose-binding lectins, GNA does not bind alpha-linked glucose.
Galanthus nivalis lectin is supplied without preservatives as a lyophilized powder.
Larger quantities are available on request.For laboratory use only.
