Try Fluka No 31160 low MW herring (sperm) DNA, it is still ridiculously cheap
and is just as good for the purpose. I have been using the same 50 gram bottle
for some years now. It needs to be titrated ( 5 ul 10 M NaOH per 50 mg ) to
be dissovled and makes a yellowish solution, but the blots are fine.
Hope this helps, while Fluka does not know.
