M66171 Cy3 azide Cy3 azide is a Cy3 fluorescent dye-labelled azide (-N₃) reagent, whose core function is to undergo specific covalent coupling with bio-molecules containing an alkyne (-C≡CH) group (e.g., nucleic acids, proteins, carbohydrates) via ‘click chemistry’ (such as copper-catalysed alkyne - alkyne cycloaddition reaction, CuAAC) to achieve specific covalent coupling with biomolecules containing alkyne (-C≡CH) groups (e.g., nucleic acids, proteins, carbohydrates), thereby realising fluorescent labelling of biomolecules.
M66170 Cy3 TSA Cy3 TSA is a Cy3 fluorescent dye-labelled tyramide signal amplification reagent, constituting a core component of TSA (Tyramide Signal Amplification) technology.
