FIG. 5.

Effect of sugars and lectins on ¹²⁵I-Cry1Ac (A) and ¹²⁵I-Cry1Ab (B) binding to H. armigera BBMV. Inhibition experiments with sugars were performed with a preincubation of the labeled protein with the sugar at 25 mM (□) or 250 mM (░⃞) for 45 min at room temperature prior to the start of the assay with the addition of the BBMV. With lectins (at 50 μg/ml [▨]), the preincubation step was done with BBMV and the assay was started with the addition of the labeled protein.
