Renee, someone on the Yahoo thread quoted an undisclosed source as suggesting that Igen is about to dip to 20. Now, to me that sounds like a fairly stupid sounding statement and I am inclined to have great doubt, but you seem to have some insight and knowledge about the stock. A contributor to that Yahoo thread requested that I question your knowledge, and I do so with a strict notice that I suspect it was a contribution from a short seller. Any thoughts or knowledge as to any possible validity of that item?

Renee, it will take a couple of months to get a better idea of surface plasmon resonance for immunoassys. They mention they can go to the picogram level, but routine assays today can do that. Also, they indicate that the POC would take 10-20 minutes, but Igen's can do it in 7 minutes so far. Another point would be that Igen's test for E. coli is 1,000 times more sensitive than the best competitor. Also, quantech has myotropin approved, but they give no numbers in their web site other than to say it is substatially they same as other tests. First impression is that Igen's is better, but I will look closer to confirm.
