Dear Dr. Fredrickson: 
I have your letter of November 17 in which you inquire 
about our role in the support or conduct of recombinant 
deoxyriobonucleic acid research and the potential 
application of the National Institutes of Health guide- 
lines to our research activities in this area. I can 
report categorically that we have no relationship to 
this field. 
Yours sincerely 
J ZB/ dh
