Triplex affinity capture

Sequence-specific DNA purification by triplex affinity capture... 

Fig. 12.5. Triplex affinity capture method. The triplex is formed in slightly acidic conditions (I). The complex is captured on paramagnetic beads and washed (11) and the duplex eluted with a mild alkaline buffer.
