Alexa Fluor® 532 dyeAlexa Fluor 532 is a yellow-fluorescent dye with excitation ideally suited for the frequency-doubled Nd:YAG laser line. Alexa Fluor 532 dye is pH-insensitive over a wide molar range, helping ensure that you get stable signals in live-cell imaging applications.

Alexa Fluor 532 conjugates exhibit an excitation maximum at 532 nm and emission maximum at 554 nm. It is particularly useful in multicolor applications, including super-resolution microscopy using dSTORM.

 

We offer Alexa Fluor 532 dye conjugated to a variety of antibodies and peptides optimized for cellular labeling and detection. In addition, reactive dye forms and protein labeling kits are available to enable you to generate your own antibody conjugates or probes.
