this is the protocol which we decided works the best and the fastest for
autosequencing on the 373A.  while i have had samples not work using this
template prep method, they could always be traced to a problem other than
the prep. method (usually primer problems).  if you still have problems
after EtOH ppt., you may need to look elsewhere for the cause.
