Batch order

DNA = ACGT   RNA = (ACGU)   2'-O-Me RNA = [ACGU]   2'-O-MOE RNA = <ACGT>   LNA = {ACGT}   Phosphorothioates = A*C*(G*U*C)


Please note:

  • insert the letter X to introduce abasic internal modifications or modifications not listed under A, C, G, T or (U).
  • Modifications must be defined in the "Manage modifications" frame.
  • You can choose up to 2 different internal modifications by sequence.

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.

Choose a linkage: By default bases are linked by a phosphodiester bond ().

Clicking on the link between two bases changes it to a phosphorothioate linkage (yellow) (). A * is then added to the sequence.
