Micrograms/Milliliter of Oligos to Picomoles/Microliter
How long is your oligo (in nucleotides)?
What is the concentration (in g/ml)?


You have pmol/l DNA
g DNA x ml x pmol x 106pg x 1 = pmol  DNA






ml 1000l 330pg 1g N l

N is the number of nucleotides and
330pg/pmol is the average molecular weight of a nucleotide.
