directed heteroduplex analysis experiences?

[Peter Wang]

There are a couple of articles in the December BioTechniques on DHDA 
(directed heteroduplex analysis), which seems like a promising and 
relatively easy way to detect mutations.  The original reference is:

Zimmerman PA, Carrington MN, Nutman TB.  "Exploiting structural 
differences among heteroduplex molecules to simplify genotyping the DQA1 
and DQB1 alleles in human lymphocyte typing", Nucleic Acids Res. 21:4541 
(1993).

I'd like to hear about netters' experience with DHDA.  I'm especially 
interested in how large a fragment people have used successfully for 
DHDA.  If people want to email me I can post a summary.  Thanks!
