Thank you very much indeed for the slides and the copy of your talk to the ACS meetings in September. Although I had read
the abstract I certainly enjoyed reading the full talk with the beautiful slides. This will help me very much in my lectures
on polynucleotide phosphorylase. The priming story would be very incomplete without the beautiful work that you people did.
Regarding the preparation of polynucleotide phosphorylase, we are still bogged down trying to get once more good active extracts
and ammonium sulfate fractions therefrom. We do not know exactly where the trouble lies but in the past few months we haven't
had much luck and have gotten preparations of low specific activity unsuitable for the further steps. I hope we shall be
able to clear this up in the near future and, once we are ready to go through with a preparation, I will let you know so that
you can come over and spend a couple of weeks with us. It will be a pleasure to have you around.
