Invitrogen™ Alexa Fluor™ 790 NHS Ester (Succinimidyl Ester), 100 µg

Invitrogen™ Alexa Fluor™ 790 NHS Ester (Succinimidyl Ester)

Alexa Fluor® 790 is a bright and photostable near-IR dye that is spectrally similar to indocyanine green (ICG) and the IRDye® 800 dye. Used for stable signal generation in imaging and flow cytometry, Alexa Fluor® 790 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. As the longest-wavelength Alexa Fluor® dye, the emission is well separated from commonly used far-red fluorophores such as Alexa Fluor® 647 dye or allophycocyanin (APC), facilitating multicolor analysis. This fluorophore is also expected to be useful for small animal in-vivo imaging (SAIVI) applications or for two-color western applications with the LI-COR® Odyssey® infrared imaging system. In addition to reactive dye formulations, we offer Alexa Fluor® 790 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® 790 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.
