AFDye 633 DBCO
AFDye™ 633 DBCO is a bright and photostable far-red fluorescent probe with excitation ideally suited to the 633 nm or 635 nm laser excitation source. AFDye™ 633 DBCO is water-soluble, pH-insensitive from pH 4 to pH 10. AFDye™ 633 spectrally is almost identical to Alexa Fluor® 633, DyLight® 633 and CF® 633 Dye. Combination of superior brightness and very low autofluorescence background signal in most biological samples in far-red spectral region allows for very sensitive detection of azide-labeled biomolecules via copper-free click reaction using AFDye™ 633 DBCO.
