If only urea changes anything... If not, then what worked for me, 
should for you. 
	We dissolve 12% acrylomide gels with 30% H2O2 (no perchlorate)
for exactly the same purpose (but protein) by overnight incubation at
+60C. Infact, it's usually done in 2 hr but who wants to wait for that?
1 ml/standard 20 ml scint. vial is OK provided that it's closed well
(we use oven). Make sure H2O2 is fresh and store it at +4C.
	Not all cocktails "like" the stuff. You might need to experiment
with different. 

Hope this helps,
