Aminooxy dyes have an aminooxy reactive group, which can be used to label a target molecule with an aldehyde or ketone group. An aminooxy group readily reacts with an aldehyde or ketone group to form a stable linkage without the use of a reducing agent. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. • UV-excitable blue fluorescent CF®350 dye has excitation/emission at 347/448 nm. • Green fluorescent CF®488A dye has excitation/emission at 490/515 nm. • Deep-red fluorescent CF®594 dye has excitation/emission at 593/614 nm. • Far-red fluorescent CF®633 dye has excitation/emission at 630/650 nm. • Far-red/near-IR fluorescent CF®770R dye has excitation/emission at 680/701 nm. • Blue fluorescent CF®405M dye has excitation/emission at 408/452 nm. • Blue fluorescent CF®405M dye has excitation/emission at 408/452 nm. • Red fluorescent CF®568 dye has excitation/emission at 562/583 nm. • Far-red fluorescent CF®640R dye has excitation/emission at 642/662 nm. • Far-red fluorescent CF®660R dye has excitation/emission at 663/682 nm.
