iFluor® 594 maleimide

AAT Bioquest's iFluor® dyes are optimized for labeling proteins, particularly antibodies. iFluor® 594 dyes have fluorescence excitation and emission maxima of ~588 nm and ~604 nm respectively. iFluor® 594 family has spectral properties similar to those of Texas Red® and Alexa Fluor® 594 (Texas Red® and Alexa Fluor® 594 are the trademarks of Invitrogen). iFluor® 594 family is pH-independent from pH 3 to 11. These spectral characteristics make this new dye family an excellent alternative to Texas Red® and Alexa Fluor® 594. Compared to Texas Red®, iFluor® 594 is much easier to conjugate with RPE with a much higher conjugation yield, and the resulting RPE-iFluor® 594 tandem has better FRET efficiency. iFluor® 555 maleimide is reasonably stable and shows good reactivity and selectivity with a thiol group.

<p>HeLa cells were stained with (Tubulin+) or without (Tubulin-) mouse anti-tubulin and then visualized with goat anti-mouse IgG - Alexa Fluor® 594 conjugate (Left) or goat anti-mouse IgG - iFluor® 594 (Right). Dye to protein ratio for each conjugate is in 2.8~3.0 range.</p>
