I felt that this was a good place to repost this information. The presentation, given by David McWilliams (Opexa CEO) on October 31, 2006 at the Towbin Life Sciences Investor Conference in New York, was freely accessible on the web. It has been converted to an easy to read and print pdf format. It's now available at http://www.msu.edu/~lyonro/Opexa06.pdf
for the time being as Lyon has graciously offered to host it on the web. Hopefully, it will answer many of the same questions that seem to keep coming up on the various boards of this forum.
