Hi southern-freaks!

I want to do a southern with genomic DNA (insect). When I digest the DNA
with Hind3 it looks fine. With EcoR1 and Xho however, there is quiete a
bit high molecular DNA that obviously has not been digested (digesting 2
hours or o/n does not change things). Does anybody have experience with
genomic southerns?

Should I proceed or start with a new preparation of DNA? 

Thanks for comments!

Gregor
