Dear All:

Trying to get amplifiable DNA from formalin-fixed polychaete specimens 
was an issue near and dear to my heart during my Ph.D.  I did attempt to 
use the France and Kocher (1996) protocol as well as a number of other 
protocols to get the DNA out and was always unsuccessful with the minute 
polychaete specimens that I had (syllids).  So, I went ahead and designed 
my own protocol--it is very simple, inexpensive and relies upon the use of 
CTAB and a bit of PCR parameter manipulation.  I am in the process of 
preparing the protocol for publication, but if anyone wants to give it a try, 
please contact me and I will be happy to send it to you!  I was able to 
extract high quality DNA and was able to get amplification (via PCR) of up 
to 500 nucleotides reliably.
