Memorandum from Dr J. K. Smith to Dr M. J. Harvey, cc Mr T. Snape, Mr E. D. Wesley, Dr R. S. Lane, re Projects with Speywood. Discusses that CF Departments practical involvement with Speywood should be limited to current work for Factor VII from Cryo-intermediate for clinical trial purposes. Further, PE seems to be most likely appealing in primary recovery for Factor VIII from Plasma , however this will be very time consuming when reaching fruition. As a result, BPL is limiting works/projects with Speywood. to current work on factor VIII from cryo-intermediate.
