描述：
Alexa Fluor® 660 is a bright and photostable far-red dye with excitation ideally suited to the 633 or 647 nm laser line. Used for stable signal generation in imaging and flow cytometry, Alexa Fluor® 660 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® 660 dye conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates optimized for cellular labeling and detection.The NHS ester (or succinimidyl ester) of Alexa Fluor® 660 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:
Fluorophore label: Alexa Fluor® 660 dye Reactive group: NHS ester Reactivity: Primary amines on proteins and ligands, amine-modified oligonucleotides Ex/Em of the conjugate: 668/698 nm Extinction coefficient: 132,000 cm-1M-1 Spectrally similar dyes: Cy5® Molecular weight: ~1100
