Dear D.N. -
Hello to everyone in the group and thank you again for the stipend for September.
How are the projects on the P-13 ---> P20 and on the cleavage of C and F by Hpa and RI progressing? Naturally I am interested
to know about any exciting results.
I have made some progress with preparation of viral stocks and SV40 DNA. The fragments are being transcribed and fingerprinted
fairly well, with the best results so far on H, J, and I. The samples of C and of E (either native or denatured) are not so
efficiently transcribed; hopefully, enough transcript to work with will be made after preparation of more DNA fragments. We
would find the Hpa enzyme useful for C of course. Has the new member of your group had any luck with the Hal and/or RII enzymes?
For the "Wilson S. Stone Memorial Award" which you pointed out to me before I left, I need a letter of recommendation
from you that should contain "a brief evaluation of the significance of the results and a paragraph about the time, place,
and nature of the candidate's timing." It should be sent to the Wilson S. Stone Memorial Award Committee, Office of
the Chancellor, The University of Texas System, P.O. Box 7969, Austin, Texas 78712. I would appreciate your help --
Gent is quite pleasant and peaceful -- very easy to adapt to. So life is nice --
Have a nice autumn. And hello to JoAnn and your sons --
