Product information "FastClick(TM) XFD350 Alkyne"
Correction Factor (260 nm): 0.25. Correction Factor (280 nm): 0.19. Extinction coefficient (cm^-1 M^-1): 19000. Excitation (nm): 343. Emission (nm): 441. FastClick(TM) XFD350 Alkyne contains both the CAG moiety of FastClick (for assisting click efficiency) and Alexa Fluor(R) 350 fluorophore (as the fluorescence tag) for developing Alexa Fluor(R) 350-based fluorescent probes. FastClick(TM) XFD350 Alkyne readily reacts with an azido-modified biomolecule under extremely mild conditions. Alexa Fluor(R) 350 is a commonly used blue fluorophore for labeling proteins, nucleic acids, or other biomolecules. It has moderate photostability and excitation that matches the 350 nm laser line. Alexa Fluor(R) is a trademark of ThermoFisher Scientific. FastClick(TM) reagents have been developed by the scientists of AAT Bioquest for enhancing the yield and reaction speed of copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction. They contain a copper-chelating ligand that significantly stabilizes the Cu(I) oxidation state and thus accelerates the click reaction. They do not require the use of an external copper-chelator (such as the common THPTA or BTTAA). The high concentration of copper chelators is known to have a detrimental effect on DNA/RNA, thus causing biocompatibility issues. The introduction of a copper-chelating moiety at the reporter molecule allows for a dramatic raise of the effective Cu(I) concentration at the reaction site and thus accelerates the reaction. Under extremely mild conditions the FastClick(TM) azides and alkynes react much faster in high yield compared to the corresponding conventional CuAAC reactions. Click chemistry was developed by K. Barry Sharpless as a robust and specific method of ligating two molecules together. Two important characteristics make click chemistry attractive for assembling biomolecules. First, click reactions are bio-orthogonal, thus the click chemistry-functionalized biomolecules would not react with the natural biomolecules that lack a clickable functional group. Second, the reactions proceed with ease under mild conditions, such as at room temperature and in aqueous media.
