1 of human genes by cloning represents the first step in 
2 pharmaceutical production of therapeutic products such 
3 as insulin, blood clotting factors, interferons, and a 
4 host of additionally medically- important products. 
5 The rapidity with which such products become 
6 available to the public will be significantly influenced 
7 by the stringency of the recombinant DNA guidelines. It 
8 seems ludicrous that some of our most productive and 
9 creative scientists have felt it necessary to carry out 
10 their investigations in Europe, because of the unreal- 
H istically stringent regulations here at home. 
12 This practice, if continued, will only serve 
13 to weaken United States biomedical science. Certainly 
14 the reduction of containment levels for eukaryotic cells 
15 and for animal viruses is very much in order. 
16 There is one additional point I would like to 
17 make. In connection with the transformation experiments 
18 which I mentioned earlier, in that connection, we have been 
19 1 solating in our laboratory a small segment of the Herpes 
20 s implex virus chromosome, containing a particular gene. 
21 We are forced to do this now by growing up large quantities 
22 of the live virus. The practice is expensive, time-consuming 
23 and cumbersome. We would prefer not to deal with large 
24 amounts of live virus, because of the risk of possible 
25 exposure to laboratory personnel. It would, of course, be
