Oligo Calculator (DNA, RNA & LNA)

This calculator can help you with calculating the following:

  • molecular weight
  • extinction coefficient
  • nmol/OD (260)
  • µg/OD (260)

Find all base notations in the list beneath the calcualtor.

 

Example: dT dA dG* dA* dC dA lT lT (remember to have a space in between bases)

 

Please note that phosphorothioated monomers shall be marked with *.

 

Also note that the 3'-end monomer in a fully phosphorothioated oligo has to be typed in as a phosphordiester base e.g. dG* lT* dG* dA* lA* lC* dC* lT (there are only 7 phosphorothioate bonds in an 8-mer long oligo).


See the analysis report in the bottom of the page.
