Set up an annealing reaction as follows:

Sense oligo 1 (100 μM) 3.0 μl
Anti-sense oligo (100 μM) 3.0 μl
10x annealing buffer* 2.0 μl
dH2O 12.0 μl

Heat at 100°C for 5 min., remove the entire heat block or water bath from the heat source, and allow to cool slowly to room temperature.
--> *10x annealing buffer: 1 M NaCl; 100 mM Tris-HCl, pH 7.4
