Bacillus thuringiensis delta-endotoxin: evidence that toxin acts at the surface of susceptible cells

P G Fast et al. Experientia. .

Abstract

Enzymically activated delta-endotoxin of Bacillus thuringiensis covalently bound to Sephadex beads, has the same effect on insect cells in tissue culture as free toxin. The effect is prevented by antitoxin antibody and heat denaturation and is not due to a nonspecific protein effect, the beads, or toxin released from the beads. The toxin, therefore, probably acts at the cell surface.
