Invitrogen Alexa Fluor 594 dye is a bright, red-fluorescent dye that can be excited using the 561 nm or 594 nm laser lines. For stable signal generation in imaging and flow cytometry, Alexa Fluor 594 dye is pH-insensitive over a wide molar range.
Probes with high fluorescence quantum yield and high photostability allow detection of low-abundance biological structures with great sensitivity. Alexa Fluor 594 dye molecules can be attached to proteins at high molar ratios without significant self-quenching, enabling brighter conjugates and more sensitive detection.
We offer Alexa Fluor 594 dye conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates optimized for cellular labeling and detection. In addition, reactive dye forms and protein labeling kits are available to allow you to generate your own antibody conjugates or probes.

Microtubules of fixed bovine pulmonary artery endothelial cells were visualized with mouse monoclonal anti–α-tubulin antibody, followed by an Alexa Fluor 350 goat anti–mouse IgG antibody. Next, the F-actin was labeled with Alexa Fluor 594 phalloidin. Finally, the cells were incubated with Alexa Fluor 488 wheat germ agglutinin to stain components of endosomal pathways. The superimposed and pseudocolored images were acquired sequentially using bandpass filter sets appropriate for DAPI, Texas Red dye, and fluorescein, respectively.

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.
