Product Description
AF 700 is a bright and photostable near-IR dye that can be excited with a xenon-arc lamp, far-red diode lasers, or dye pumped lasers operating in the 675–700 nm range. Used for stable signal generation in imaging and flow cytometry, AF 700 dye is water soluble and pH-insensitive from pH 4 to pH 10. Fluorescence of this long-wavelength AF dye is not visible to the human eye but is readily detected by most imaging systems. In addition to reactive dye formulations, we offer AF 700 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 AF 700 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. Fluorophore label: AF 700 dye Reactive group: NHS ester Reactivity: Primary amines on proteins and ligands, amine-modified oligonucleotides Ex/Em of the conjugate: 702/723 nm Extinction coefficient: 205,000 cm-1M-1 Molecular weight: ∼1400
