Hi!!  We here at the National Analytical Ultracentrifugation Facility
at the University of Connecticut have been asked more and more lately about
the feasibility of doing melting studies on various protein associates and
DNA oligomers at elevated temperatures.  Since the XLA only goes to 40, we
have modified one of our Es so that it will go to 70.  I know that years ago
Beckman made a high temperature accessory for the E that supposedly allowed
it to go to 100.  Does anyone out there have one or has the plans for it
(Steve Shire???).  Some years ago I tried to get a copy of the plans from
Beckman with no luck.
      BUT-- how many feel that such a capability is needed now on the XLA?
I know that the Beckman people
are reading these blurbs and that we may be able to affect
policy if there is enough demand.  I also feel that it might be a plus for
their prep, as such a capability might cause new prep techniques to be devised.
If they build it, the uses will come!  In any case let's discuss this!
