Alexa 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.

Molecular Probes Handbook
The significantly revised 11th Edition is the most complete fluorescence labeling and detection reference available. The Molecular Probes Handbook can help you achieve the best experimental results for your fluorescence labeling and detection experiments. View the handbook online or order your own copy.
Antifade reagents suppress photobleaching and preserve the signals of your fluorescently labeled target molecules. They offer excellent compatibility with a multitude of dyes across the spectrum, making them especially valuable tools for multicolor applications. For added convenience, some formulations include the nuclear counterstain DAPI, eliminating the need for a separate counterstaining step.
Cell stain tool
Stain your own cell by using our simulation tool to develop reproducible results with many of our signature fluorescent dyes. Develop your multiplexing strategy for antibody probes, reactive dyes, and counterstains to create your perfectly labeled fluorescent cell.
Plot and compare spectra and check the spectral compatibility for common fluorophores including all of the fluorescent probes from Thermo Fisher Scientific. The Fluorescence SpectraViewer tool is formatted for both microscope imaging and flow cytometry applications.
