i've been working (passively) on a protocol to do that for months.  despite
changing almost every possible parameter of the situation (template and
primer concentration, cycling times, clean up, etc.) nothing seems to work.
 from your mail address at ABI, i'm surprised you asked this question. 
it's been my impression that the party line at ABI/PE is that this doesn't
work.  i don't really know why it doesn't work, but i'm beginning to agree
with them.

so far, TA cloning is the fastest and best way that i've found to get the
sequencing to work.  it takes way more time than i would like, but i think
it's the best choice.
