I have recently done an isopropanol precipitation of plasmid DNA on a
solution eluted from a Qiagen Maxiprep column. On the addition of the
isopropanol, a white cloudy precipitate formed which floated as a layer on
top. Does anyone know what that might be?
I was told that DNA precipitated from isopropanol would look quite glassy
and I shouldn't be able to see it. So could the cloudy layer be salts?
Thanks for any insight.
