iFluor® IRD 800 CW Maleimide

iFluor® IRD 800 CW maleimide is a near-infrared thiol-reactive dye chemically identical to IRDye® 800CW (LI-COR) that enables site-specific protein labeling for in vivo imaging with minimal background fluorescence.

Thiol-Reactive NIR Probe: Maleimide group forms stable thioether bonds with cysteines
Deep Tissue Imaging: Ex/Em = 774/789 nm penetrates >1 cm tissue with minimal scatter
pH-Stable Conjugation: Reactive at pH 6.5–7.5 for site-specific protein labeling

iFluor® IRD 800 CW Maleimide has the same chemical structure as the IRDye® 800 CW Maleimide (IRDye® is the trademark of LI-COR).

Overview

iFluor® IRD 800 CW Maleimide has the same chemical structure as the IRDye® 800 CW Maleimide (IRDye® is the trademark of LI-COR). IRD 800CW Maleimide is a thiol-reactive near-infrared (NIR) fluorescent dye with good water solubility. It can be used to label peptides, antibodies, and other thiol-containing biomolecules such as thiol-modified oligos. The IRD 800CW conjugates can be used as a probe for Western blot, flow cytometry, immunocytochemical assays, including In-Cell Western assays and On-Cell Western cell-based assays, protein arrays, microscopy, tissue section imaging, and in vivo imaging. IRD 800CW dye-conjugated probes are also used for fluorescence imaging-based cancer diagnosis.
