Alexa Fluor® 594 Antibody Conjugates

Visualize proteins with the bright red fluorescence and efficient light absorption of Alexa Fluor 594. The longer Ex/Em wavelengths of Alexa Fluor 594 conjugates offer mild tissue penetration with minimal background interference. The excellent photostability of these conjugates allows them to withstand prolonged light exposure without photobleaching.

Attributes

The excitation spectrum of Alexa Fluor 594 is demonstrated as the dashed orange line while the emission spectrum is shown in solid orange. For multiplexed labeling experiments, selecting antibodies conjugated to fluorophores with limited excitation and/or emission overlap yields the best results.

Applications in Research

There are several advantages afforded by Alexa Fluor 594 conjugates that researchers can take advantage of:

• Alexa Fluor 594 can be attached to proteins at high molar ratios without significant self-quenching, enabling brighter conjugates and more sensitive detection.
• Although the emission of the Alexa Fluor 594 conjugates not in the far-red emission range, Alexa Fluor 594 conjugates benefit from their long wavelength for mild tissue penetration and reduced autofluorescence, limiting background noise from blue and green light.
• The high brightness and photostability of Alexa Fluor 594 allows the detection of low abundance molecules with high sensitivity.
• Alexa Fluor 594 is available with various reactive groups to allow conjugation with most biomolecules, permitting access to amine, thiol, glycan, or other conjugation chemistries.

Alexa Fluor 594 is highly stable and can be used with several detection systems and is suitable for numerous multiplexed applications, including:

• Immunofluorescence
• Flow cytometry and spectral flow cytometry
• Immunohistochemistry
• Spatial biology
• Super Resolution Microscopy (SRM)
