This product is used for the attachment of the FLAG-tag by copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC), the prototypical reaction of click chemistry, as described for example by Wang and coworkers. In addition, Azido-PEG3-FLAG contains a PEG-linker. The resulting FLAG-tagged molecules can be detected or purified immunologically, using dye labeled, enzyme coupled or, for purification, immobilized anti-FLAG antibodies.
