Sulfo-Cyanine5 azide

Product Introduction

Water-soluble Cyanine5 dye azide for Click chemistry. Bright and photostable dye with red fluorescence. The reagent has high water solubility. Due to high solubility and hydrophilicity, the dye can be used for labeling biomolecules in native, purely aqueous conditions. This reagent, as opposed to competing products, is supplied as an alkaline metal salt and not triethylammonium salt. Therefore, it is a powder which is easy to handle and dispense.Sulfo-Cyanine5 is an analog of Cy5®, a very popular fluorophore, therefore this reagent is compatible to a wide range of standard fluorescent instrumentation such as imagers, plate readers, and microscopes.
