The problem is that the Sarab Wrap is sticking badly to the gel therefore either it does not come off easily or my gel remains stick.I am using 35S-dATP therefore I need to remove the wrap before exposing. Any suggestions will be appreciated. Ashu
is there some reason for trying to remove the urea...
we've found that the fixation and removal of urea is not necessary...
in fact, fixation tends to "blurr" the sequencing bands.
if your gel is sticking to the saran wrap, you may not be drying the
gel long enough...make sure that there is a good seal on the gel dryer
hope it helps
