Alexa Fluor 647 NHS Ester (Succinimidyl Ester)
Alexa Fluor™ 647 is a bright and photostable far-red dye with excitation ideally suited to the 633 nm laser line. Used for stable signal generation in imaging and flow cytometry, Alexa Fluor™ 647 dye is water soluble and pH-insensitive from pH 4 to pH 10. Fluorescence of this long-wavelength Alexa Fluor™ dye is not visible to the human eye but is readily detected by most imaging systems. In addition to reactive dye formulations, we offer Alexa Fluor™ 647 dye conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates optimized for cellular labeling and detection (learn more).
The NHS ester (or succinimidyl ester) of Alexa Fluor™ 647 is the most popular tool for conjugating this dye to a protein or antibody. NHS esters can be used to label to the primary amines (R-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The resulting Alexa Fluor™ conjugate will exhibit brighter fluorescence and greater photostability than the conjugates of other spectrally similar fluorophores.
Detailed information about this AlexaFluor™ NHS ester:
