Your earlier post gave me the impression you agreed that Bt is a
lectin. Anyway, I cite Pusztai's opinion that Bt toxin is a lectin
based on a private message forwarded to me by one who asked him
directly about it. I also remember that he said so in a transcript
of his testimony at the British parliament (but I'm still trying to
locate that transcript). This was also confirmed (in that transcript)
by another scientist who actually helped kick him out of Rowett.
I know this is not an unacceptable source, until I produce that
transcript. I'm working on it. If subsequent research finally
determines that Bt toxin is not a lectin, I will of course drop that
paragraph in the document.
