Long Arabidopsis PCR

[Wayne M. Barnes, Ph.D.]

Dear Cathy and Kim,

     We are also trying long PCR on Arabidopsis DNA.  So far, we can get 
the LEAFY sequence from genbank to amplify very well, using primers that 
are 33 nt from each end of its 7 kb.

     It's best to have some anti-Taq antibodies in there, using KlentaqLA 
as the enzyme.  Our template DNA was from axenic green plant protoplasts.  
We are evaluating how best to prepare the template DNA.  Other than that, 
we have not much advice to give, yet.  If you like, we can be in touch when 
we get more impressive targets to work.
