A Glucose binding lectin from Leucaena leucocephala seeds and its mitogenic activity against human lymphocytes.

Lectins are a specialized group of proteins with immense biological properties and applications. This study describes the purification and characterization of a lectin from Leucaena leucocephala seeds, a plant belonging to the Fabaceae family. Leucaena leucocephala lectin (LLL) was purified by a two-step purification method involving DEAE-cellulose anion exchange chromatography and Sephadex G-75 size exclusion chromatography.
