running ssDNA (30-1000nt) in denatured conditions

Hi all,

I am trying to run DNA under denatured conditions. Has anyone run single
stranded DNA (30nt to 1000nt) under denatured conditions.

I am trying to decide whether to run a low percentage urea acrylamide gel or
an alkaline agarose gel. Any thoughts/ideas? I am thinking maybe running a
low percentage (3-4%) urea acrylamide gel, but wonder that it may not be
able to resolve ssDNA above couple hundred nucleotides in length even in low
acrylamide such as 3-4%? Any thoughts? Has anyone run alkaline agaorse for
ssDNA 30nt-1000nt? If so, may I ask for your conditions?

THANKS!

Tracy

Hi...
I m currently using 20% Polyacrylamide gel(PAGE)for ssDNA (20-30 nt)
and 15% PAGE for ssDNA of 30-50mer.Its giving good results...Hope this
will help u..For more lengthy strans i think u should try 8-10% PAGE.
