Self ligation of PCR products

[Steven Kirov]

Hi there,
Generally if your PCR primers don't have PO4 on their 5' end there is no 
way to get ligation (or at least this is what is accepted up to now - 
prove diopposite and get a Nobel prize?).
If they do have, than you should know, that part of the molecules have G, 
C or T as an extension instead of A (though a small percent). And also as 
 our colleague Hiranya Roychowdhury writes there are also blunt end ones.
Greetings to all and Merry Christmas and so on...
