WebOct 14, 2014 · For the first time, a novel EpCAM aptamer (SYL3C)-DIBO-AF594 fluorescent conjugate was synthesised by bioorthogonal chemistry utilizing a strain promoted alkyne-azide cycloaddition (copper free click) reaction (SPAAC). The ligation efficiency of SPAAC was improved by freeze-thaw cycles. The obtained … WebImproved copper free SPAAC reagents. We have developed a compelling, alternative ‘click’ reagent containing a strained triple bond that does not require copper catalysis. These reagents are used in strain-promoted azide-alkyne cycloaddition reactions (SPAACs) and are essential for applications in the biological sciences. WebJul 20, 2011 · Abstract. 1,3-Dipolar [3 + 2] cycloaddition between azides and alkynes--an archetypal "click" chemistry--has been used increasingly for the functionalization of nucleic acids. Copper (I)-catalyzed 1,3-dipolar cycloaddition reactions between alkyne-tagged DNA molecules and azides work well, but they require optimization of multiple reagents, and ... rootball tree planting services
