Preparation of carbohydrate-iron complexes as electron dense receptors for membrane bound lectins

Summary The preparation of a mannan-iron complex is described. The mannan-iron complex can be used for electron microscopic demonstration of membrane bound Concanavalin A or Lens culinaris lectin because the high reactivity of these lectins toward the mannan.
