Long trebler phosphoramidite

Description

After the Long trebler phosphoramidite is condensed by the triple condensate, three DNA branches begin to grow simultaneously with each step of the synthesis. Deblock of this construct gives rise to DNA containing a branching point. One arm stem is attached to the branch point with its 5-end, and other arms branches are attached with their 3-ends. Reverse amidites can be used to prepare constructs with different branch orientations.
