Narcissus pseudonarcissus (daffodil) lectin (NPL, NPA), Unconjugated

Narcissus Pseudonarcissus (Daffodil) Lectin (NPL, NPA), Unconjugated, 5 mg, isolated from daffodil bulbs, has a specificity toward alpha-linked mannose, preferring polymannose structures containing (alpha-1,6) linkages. Binding to mannose polymers can occur via internal mannose residues and is not dependent on structural integrity of a non-reducing end sugar. NPL also binds some galactomannans and differs in other binding characteristics from a related lectin, Galanthus nivalis lectin. Unlike Con A, LCA, or PSA, NPL does not bind glucose.
