iFluor® 405 amine
AAT Bioquest's iFluor® dyes are optimized for labeling proteins, particularly antibodies. These dyes are bright, photostable, and have minimal quenching on proteins. They can be well excited by the major laser lines of fluorescence instruments (e.g., 350, 405, 488, 555, and 633 nm). iFluor® 405 dyes have fluorescence excitation and emission maxima of ~403 nm and ~427 nm respectively. These spectral characteristics make them an excellent alternative to Alexa Fluor® 405 labeling dye (Alexa Fluor® is the trademark of Invitrogen). iFluor® 405 amine is stable and used for modifying carbonyl groups (e.g., aldehyde and carboxy groups).
