- Hi,
-
- In the course of my work I have to extract DNA from muscle
- biopsies. Since I have to deal with quite a number of samples,
- I have set up a simple, fast and efficient method, basically
- constructed from a number of published protocols (in short,
- I homog. the biopsies, stew the homogenate in ProK, PhOH/CHCl3
- extract, NH4Ac precipitate, EtOH wash and, presto, the DNA is
- ready to be dissolved in T10E0.1!).
-
- The weak point in the protocol (yeah, nothing is perfect...), is
- yield. In general I have no problems, ending up with more DNA then
- I need, even for complex analysis; sometimes, however, I have to
- extract DNA from really _tiny, tiny_ (not to say ridiculously small!)
- biopsies. It's then that trouble knocks on my door...
-
- So, does anyone have a quick and efficient protocol for extracting
- DNA from muscle biopsies?
-
- Has anyone worked with the Qiagen columns? (using muscle tissue, of course!)
-
- Thanks for all the info,
-

- PS - Should anyone want a more detailed version of the protocol I
- now use, I'd be more then happy to share it - just drop me a line
- to pamaga@biobase.aau.dk
