A series of red fluorescent dyes were synthesized using 3-N,N-diethylaminophenol. Their structures were characterized by 1H NMR, 13C NMR, IR and HRMS. The optical properties of these dyes were detected. Bovine serum albumin was labeled by new dyes. The fluorescence signal values of these dyes and cyanine-3 (Cy3) in lectin microarrays were compared. The results show that the maximum emission wavelengths of these dyes are above 600 nm and the Stokes shifts are about 70 nm. The dye/protein (D/P) labeling efficiencies of these dyes are as high as 1.5~1.8. The fluorescence signal of new dyes is equal to Cy3 in lectin microarray. Hence, these dyes can also be used as fluorescent labels for detection of sugar chain changes in lectin microarrays.

Key words: fluorescent dye, synthesis, spectral property, protein label, lectins microarray
