Hi Terezia

Whenever I have worked with older material I have allways isolated DNA with the CTAB method, but modified, so the concentration is 2 x CTAB.

Dear Nadia and Britta, thanks for your answers!

My pleasure

Thanks for your answer..

Hi Terezia

I am using CTAB buffer in my lab  for extracting DNA from muscle tissue of different fish species. Here I  found good band result  in gel. I think you can try. After  using the CTAB protocol  kindly inform your result.
