Overview

Rabbit Anti-Alexa Fluor 750 Antibody, iFluor® 647-Labeled is a polyclonal antibody that specifically binds to Alexa Fluor® 750-conjugated molecules and is directly labeled with iFluor® 647, a far-red fluorophore with excitation/emission maxima of ~656/670 nm. This direct labeling allows for one-step detection of Alexa Fluor® 750 targets without the need for a secondary antibody. The antibody may cross-react with similar near-infrared fluorophores such as iFluor® 750, ATTO 740, and DyLight® 755. Its spectral compatibility makes it iideal for signal amplification, conjugation verification, and multiplexed fluorescence detection. Alexa Fluor® and DyLight® are registered trademarks of Thermo Fisher Scientific.
