FIGURE 3.

Cry1Ab domain II loop 2 and domain III mutants are structurally stable. A, SDS-PAGE electrophoresis pattern of trypsin activated Cry1Ab (lane 1), L511A (lane 2), R368A/R369A (lane 3), and F371A (lane 4) toxins. B, Western blot of pure oligomer samples obtained after size exclusion chromatography of toxin samples activated in the presence of cadherin fragment CR7-CR12. Cry1Ab (lane 1), L511A (lane 2), R368A/R369A (lane 3), and F371A (lane 4) toxins are shown. Molecular mass markers are shown at the left of the figure.
