Hi Danielle

you'll need further information to convert that. you'll need the molecular weight of the cel-mir-39.

i believe its 7018.2 g/mole

( 5'- rUrCrA rCrCrG rGrGrU rGrUrA rArArU rCrArG rCrUrU rG -3' )

ok

then, your stock is:

1600 fMol/ul = 1600x10-15 Mol/ul = 1600x10-15 * 7018.2 g/ul = 11229120x10-15 g/ul = 11.23 ng/ul

you then need to go from 11.23 to 2 ng/ul:

for instance, add 1ul of your stock to 4.615ul of pure water to get a 5.615 ul solution at 2ng/ul...

on higher volumes of course the results will be better, to address the pipetting issues.

all the best
