Rabbit Anti-Alexa Fluor 350 Antibody, iFluor® 647-Labeled

Product key features

Rabbit Anti-Alexa Fluor 350 Antibody, iFluor® 647-Labeled is a polyclonal antibody labeled with iFluor® 647 for detecting Alexa Fluor® 350 conjugates.
  • Direct Detection: iFluor® 647 enables one-step visualization of Alexa Fluor® 350 targets.
  • Spectrally Distinct: Far-red emission avoids overlap with blue-channel fluorophores.
  • Polyclonal Format: Rabbit-derived with broad epitope recognition.
  • Multipurpose Use: Ideal for signal amplification, conjugation verification, and multiplexed fluorescence detection.

Product description

Rabbit Anti-Alexa Fluor 350 Antibody, iFluor® 647-Labeled is a polyclonal antibody that specifically binds to Alexa Fluor® 350-conjugated molecules and is directly labeled with iFluor® 647, a far-red fluorophore with excitation/emission maxima of ~656/670 nm. This configuration allows for one-step fluorescence detection without the need for secondary antibodies.

The antibody may cross-react with structurally similar fluorophores such as iFluor® 350, AMCA, and Cascade Blue®. The far-red emission of iFluor® 647 avoids spectral overlap with blue fluorophores, making this reagent especially effective in signal amplification, conjugation verification, and multiplexed fluorescence detection making it a versatile tool for imaging and analytical workflows.

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