Cyanine 5 alkyne (A270160)

Cyanine 5 alkyne

Cyanine 5 alkyne for Click Chemistry, an analog of Cy5® alkyne. With this product, deeply colored, and photostable Cyanine 5 fluorophore can be attached to various molecules via Click Chemistry reaction with azides. This alkyne is non-water soluble, but it can be dissolved in DMF or DMSO prior to reaction, and added to aqueous reaction mixture. The labeling reaction is very efficient, and high-yielding. Various substrates bearing azides can be used for the labeling, including azido-labeled biomolecules, polymers, and solid surfaces.
