Sensitive DNA probe for photochemical ligation prepared in click chemistry

Abstract

We report a new photosensitive probe, that takes advantage of the electronic structural changes associated with the triazole ring formed in the Cu(I)-catalyzed Huisgen 1,3-dipolar cycloaddition. We succeeded in performing photoligation on the second time scale. Huisgen cycloaddition are employed to various labeling. As an example, we report a procedure for preparing the DNA probe for quick SNP typing.
