FIG. 5.

(A) Specific binding of ¹²⁵I-Cry1Aa to increasing concentrations of BBMVs from last-instar L. monacha larvae. (B) Specific binding of ¹²⁵I-Cry1Ac to increasing concentrations of BBMVs from last-instar L. monacha larvae. (C) Specific binding of ¹²⁵I-Cry1Ab to increasing concentrations of BBMVs from last-instar L. monacha larvae. (D) Specific binding of ¹²⁵I-Cry1Ab to increasing concentrations of BBMVs from first- and second-instar L. monacha larvae. In all cases, the reaction volume was 0.1 ml and for each point nonspecific binding was subtracted from total binding (see the legend to Fig. 2).
