CF® dye-dUTP can be used for TUNEL assay, or to synthesize labeled DNA probes for in situ hybridization and nucleic acid blotting applications. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. • Blue fluorescent CF®405S dye has excitation/emission at 404/431 nm. • Green fluorescent CF®488A dye has excitation/emission at 490/515 nm. • Orange fluorescent CF®543 dye has excitation/emission at 541/560 nm. • Red fluorescent CF®568 dye has excitation/emission at 562/583 nm. • Deep-red fluorescent CF®594 dye has excitation/emission at 593/614 nm. • Far-red fluorescent CF®640R dye has excitation/emission at 642/662 nm. • Far-red/near-IR fluorescent CF®680R dye has excitation/emission at 680/701 nm.
