Details

Alexa Fluor™ 647 Carboxylic Acid is a non-reactive form of Alexa Fluor™ 647 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 (Cat. No. E2247). Characteristics of Alexa Fluor™ 647 dye include: Laser line: 647 nm Common filter set: Cy™ 5 Excitation maxima: 650 nm Emission maxima: 665 nm More About Alexa Fluor™ 647 Dye Alexa Fluor™ 647 dye is a bright, far-red-fluorescent dye with excitation ideally suited for the 594 nm or 633 nm laser lines. It is ideal for imaging low-abundance targets, especially in fixed cells. Alexa Fluor™ 647 dye is commonly used with DAPI, and Alexa Fluor™ 488 and 594 dyes for multiplexing.

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.
