Rabbit Anti-Alexa Fluor 594 Antibody, iFluor® 594-Labeled

Product key features

Rabbit Anti-Alexa Fluor 594 Antibody, iFluor® 594-Labeled is used for detecting Alexa Fluor® 594 conjugates in red-fluorescence detection workflows.

  • iFluor® 594 Labeled: Emits bright red signal with minimal background.
  • Spectrally Matched Fluorophores: iFluor® 594 and Alexa Fluor® 594 share nearly identical spectra for better signal amplification.
  • Direct Detection: Enables single-step fluorescence workflows.
  • Multipurpose Use: Ideal for signal amplification, conjugation verification, and multiplexed fluorescence detection.

Product description

Rabbit Anti-Alexa Fluor 594 Antibody, iFluor® 594-Labeled is a polyclonal antibody that selectively targets Alexa Fluor® 594-conjugated biomolecules. It is directly conjugated to iFluor® 594, a bright red-emitting fluorophore with excitation/emission maxima of ~590/617 nm, enabling robust one-step detection of Alexa Fluor® 594-labeled targets in immunofluorescence, microscopy, and flow cytometry.

This antibody may cross-react with spectrally similar dyes such as DyLight® 594, and ATTO 594. It is ideal for signal amplification in low-abundance target detection, verifying dye conjugation efficiency, and performing multiplex fluorescence assays in various applications.

Alexa Fluor® and DyLight® are registered trademarks of Thermo Fisher Scientific.
