...I think that the data for the recombination, and the origin, through the nude mice is very convincing. I have to say that. And what is difficult for me is the next step of how it contaminated the laboratories. You know, you can say that it's in a reagent, it's in a tube, but every laboratory, including the Lo laboratory, uses multiple controls on every run, and they are always negative, and we have looked for mouse genome first by a very very sensitive nested PCR that was a hundred fold more sensitive than the PCR used to detect the polytropic viruses, and did not find any genomic DNA.
Then used your first IAP assay, and then your improved IAP assay, exactly as you gave us the formula, and do not find any contamination.
Now you can never rule out contamination 100%. But it isn't there, and i still don't know why the negative controls in Judy's lab are negative and why on the panels that have been done thus far, she's been able to distinguish samples from patients versus negative control.

I'm not denying that there may be contamination but I just wanted to put this into perspective...
