biopharm, I don't know. PPHM was quite clear about it. Now that being said, and given the sabotage, they may have made a quite precise statement that they didn't use the detection techniques used in the other trials.
They never said they didn't use ANY. Remains to be seen. Hard to say.
Peregrine Pharmaceuticals the Microsoft of Biotechnology! All In My Opinion. I am not advising anything, nor accusing anyone.
