One time while I was precipitating my DNA following elution from
the Qiagen column, I took the initiative to cut one of the columns
open.  The consistency of the matrix didn't seem like glass milk.
To be technical, it was mushier.
Is this just a ploy by the fine people at Qiagen to hide the fact
that it is in fact just glass milk, or is it actually something
different?
