ALEXA FLUOR 532 FREE ACID 5 mg，A33078，Invitrogen

Alexa Fluor® 532 Carboxylic Acid is a non-reactive form of Alexa Fluor® 532 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® 532 dye include:

• Laser line: 532 nm
• Excitation maxima: 530 nm
• Emission maxima: 554 nm

More About Alexa Fluor® 532 Dye
The Alexa Fluor® 532 dye and its conjugates have excitation and emission spectra that are intermediate between those of the green-fluorescent Alexa Fluor 488 dye and the orange-fluorescent Alexa Fluor 546 dye, making it an ideal dye for use with 532 excitation sources, including the frequency-doubled Nd-Yag laser.

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.
