Overview

Short to medium length (up to 120 bp) fragments of dsDNA can be generated directly from two complementary single-stranded oligonucleotides. Custom overhangs for ligation or In-Fusion can be introduced as well, simply by having some non-complementary ends. The two single-stranded Oligos then need to be annealed into a double-stranded fragment.

The idea is to heat up the mixture to close to 100 C and let it slowly cool down to room temperature over the course of one hour.

Materials

  • Thermocycler
  • 10x annealing buffer, final (1x) concentration: 10mM Tris-HCl, 50mM NaCl, 1mM EDTA
    • closest match is NEB Buffer 2 (1x: 10mM TrisHCl, 50mM NaCl, 10mM MgCl2, 1mM DTT)

Procedure
