Hippeastrum hybrid Lectin (HHL) - Pure

Affinity purified Hippeastrum hybrid lectin (HHL) consists of four subunits of identical size. It binds only to (?-1,3) and (?-1,6) linked mannosyl units of ?-mannose residues. HHL reacts not only with terminal but also with internal ?-D-mannosyl residues. Lectin appears to possess extended binding sites complementary to at least three 1,6-linked ?-mannosyl. HHL also binds to some yeast galactomannans.
