Binding of N-Acetyl-neuraminic Acid by Wheat-germ Agglutinin

Abstract

SURFACE changes on cell membranes are thought to play a significant role in malignant transformation. The agglutination of transformed cells by plant lectins reflects some of the altered surface properties of these cells1–3. Wheat-germ agglutinin (WGA) binds nearly equally to both normal and transformed cells4; however, with few exceptions, only transformed cells are agglutinated5–7. Agglutination by this lectin is reversible and is inhibited by N-acetylglucosamine, di-N-acetyl chitobiose, and ovomucoid8.
