What is the detection sensitivity of silver staining of DNA? can one detect
single ng quantities (i.e. 1 pmole of oligo) or does one need like 100ng
(100 pmole of oligo)? I ask becuase i usually kinase my oligos after
synthesis to test them, and gel purify them after I know the approx. yield,
but we have some 5' blocked oligos that can't be kinased, and I don't want
to start with tailing with cordecypin. Not to mention it would be nice to
slip the labelling step.

TIA

Jason.
