I have problems to transfert RNA on membrane after using Glyoxal/DMSO denaturing agarose electrophoresis.system. RNA seems to have good electrophoresis behaviour, but I am not able to hybridize it after transfert on Nylon membrane (Amersham Hybond N+). If you are familiar with northern after Glyoxal/DMSO electrophoresis,I would gre atly appreciate to have more explanation on the techniques you use, and more details on the type of membrane (nitrocellulose, nylon ...) which works well.
