Thank you Lykiri, as you probably know, Allen Turner use to work for Northwest Biotherapeutics, and he along with Dr. Marnix Bosch and others at NWBio, invented and patented the Tangential Flow Filtration (TFF) device, which is used to manufacture DCVax Direct:
Allen Turner has since gone on to work with other BPs, and another co-inventor (Patricia Ann Lodge) went on to work for Charles River Laboratories (CRL) as a consultant.
