Rabbit Anti-Alexa Fluor 594 Antibody, iFluor® 350-Labeled

Product key features

Rabbit Anti-Alexa Fluor 594 Antibody, iFluor® 350-Labeled is a polyclonal antibody labeled with iFluor® 350 for direct detection of Alexa Fluor® 594 conjugates.

Direct Detection: iFluor® 350 enables single-step fluorescence detection of Alexa Fluor® 594 targets.
Spectrally Distinct: Blue emission avoids overlap with orange-red fluorophores.
Polyclonal Format: Rabbit-derived with broad recognition of Alexa Fluor® 594 conjugates.
Multipurpose Use: Ideal for signal amplification, conjugation verification, and multiplexed fluorescence detection.

Product description

Rabbit Anti-Alexa Fluor 594 Antibody, iFluor® 350-Labeled is a polyclonal antibody that specifically binds to Alexa Fluor® 594-conjugated molecules and is directly labeled with iFluor® 350, a bright, UV-excitable blue fluorophore. This configuration allows single-step fluorescence detection without requiring a secondary antibody.

The antibody may cross-react with fluorophores similar to Alexa Fluor® 594, such as iFluor® 594, ATTO 594, and Texas Red®. Its blue emission is well-separated from orange-red dyes, making it ideal for signal amplification, conjugation verification, and multiplexed fluorescence detection.

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