Use of common plant lectins for isolation and characterization of constitutive and developmentally regulated cell surface associated glycoproteins of Dictyostelium discoideum.

Glycoproteins as a class of molecules have been implicated as serving crucial roles in cell recognition events. Using 3 common plant lectins, we have isolated and identified a number of cell surface associated glycoproteins. The appearance of at least 5 of these proteins is under developmental regulation.
