Hi to all!
In my lab, like almost any molecular biology lab, we do DNA sequencing
here and there. The wierd and sometimes most fustrating part apart from
pouring gels is fixing them. I have used the standard 10% AcOH/10% MeOH
solution to fix them. Many in the institute I work in use 20% EtOH. What
are the advantages and disadvantages. If you Netters out there use any
other solutions other than the above please give me your ideas.
Back to fixing gels. Gels seem to have the ability to float off the glass
plate while fixing, even w/o intervention (eg shaking and disturbances).
Usually this results in what I call reconstructive gel surgery prior to
drying.What is the main problem here? Dirty glass plates or my lab has a
zero-G spot? I have experienced gels warping when fixing too. When I mean
warping I mean shrinks and swellings.
If you have other problems and solutions to fixing gels please send them
to me. I would be happy to compile your ideas/solutions to the above
problems or even the problems you encounter.
