Alexa Fluor™ 633 Carboxylic Acid, tris(triethylammonium) salt

Product introduction:Alexa Fluor™ 633 Carboxylic Acid is a non-reactive form of Alexa Fluor™ 633 that can be used as a reference standard for dye-conjugates. Additionally, this carboxylic acid derivative can be converted to an amine-reactive ester using standard chemical techniques or coupled to hydrazines, hydroxylamines, and amines in aqueous solution using water-soluble carbodiimides such as EDAC.Characteristics of Alexa Fluor™ 633 dye include:• Laser line: 633 or 635 nm:• Excitation maxima: 632 nm:• Emission maxima: 647 nm:More About Alexa Fluor™ 633 Dye:The Alexa Fluor 633 dye and its conjugates are a perfect match to the 633 nm spectra line of the He-Ne laser or the 635 nm spectral line of red diode lasers. This and other far-red fluorescent Alexa Fluor™ dyes are important labels for fluorescence imaging because their spectra are beyond the range of most sample autofluorescence.Discover the Benefits of the Alexa Fluor™ Dye Series:Compared to traditional dyes, Alexa Fluor™ dyes are brighter, more photostable, and more pH-resistant between pH 4 and 10. And generally when using Alexa Fluor™ dyes, higher degrees of labeling can be achieved without intramolecular quenching.
