DUSSELDORF, Germany – Buoyed by Monday's series of workshops on the dos and don'ts of finding partners and striking deals (and learning to live with them afterward), companies attending BIO-Europe Fall 2011 rolled up their sleeves Tuesday and started in on what they had really come for: bare knuckles partnering. With 14,661 scheduled one-to-one meetings – and countless more unscheduled, impromptu exchanges – it's unlikely that any aspect of biotechnology will not receive an airing at this event.
