Hydrophilic, alkyne-reactive, long-lifetime reagent for click chemistry containing one azide function. Azides react with C≡C-triple bonds in either a Cu(I)-catalyzed or Cu-free 1,3-dipolar cycloaddition reaction to triazole.
Applications
Click Chemistry reagent.
Advantages
Perfectly suited for excitation with the 532-nm laser
Good aqueous solubility:this label does not alter the solubility of the protein conjugate
Low molecular weight: Seta-555 does not add substantial mass to the conjugates
Photostability: Higher photostability as compared to Alexa Fluor™ 555 or Cy3
Ideal for non-radioactive labeling of alkyne-modified proteins, DNA and oligonucleotides
