Add internal modifications:
When applicable, choose your internal modification by clicking on the black triangle ( empty-box ) related to the base to modify.

Modified bases are displayed as a plain dark box ( plain-box ).

X units ( x-chemist ) must always have an internal modification.

Valid for orders placed before 10 a.m. (CET). Your order must contain up to maximum 24 oligonucleotides and have the same day shipping method.

Get free primers

For each Probe (Double-Dye, Molecular Beacon or MGB), you can receive 2 free primers.
Each primer must be 15-30 DNA bases, unmodified and RP-Cartridge–Gold purified.

The synthesis scale of the primers :

  • must be similar to the Double-Dye Probe or Molecular Beacon one (10, 40, 200 or 1000 nmol)
  • must be selected according to the MGB Probe delivered quantity as report in the quantity table
