nvitrogen，Alexa Fluor™ 647 Carboxylic Acid（试剂）_5mg

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. Learn more about this dye and related products.
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.
