Cy5-PEG-methyltetrazine, MW 5,000 is a water-soluble linker of Cyanine5 fluorophore with a terminal tetrazine group. The terminal methyltetrazine enables fast click reactions with TCO (trans-cycloctene). The hydrophilic polyPEG chain increases the water solubility of the overall compound allowing for the higher conjugation efficiency. This reagent is compatible to a wide range of standard fluorescent instrumentation such as imagers, plate readers, and microscopes. Reagent grade, for research purpose.
