73. citation?

Sorry, but I don't believe that statement is correct. It's my impression that the primary difference in crystalline and non-crystalline forms results not from any difference in the expressed protein, but rather from differences in the intracellular environment where it's expressed. AND in any event Bt in any form is nonactive in vertebrate guts. Please provide a citation providing data that demonstrates otherwise. I just haven't seen anything like what you suggest (other than in the hysterical popular literature, e.g. Mercola type stuff).
