This kit contains everything you need to label antibodies or other proteins with a fluorescent CF® dye succinimidyl ester (CF® dye SE). Each kit contains reagents for three labeling reactions of up to 1 mg protein per reaction. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. • Orange fluorescent CF®532 dye has excitation/emission at 527/558 nm. • Orange fluorescent CF®543 dye has excitation/emission at 541/560 nm. • UV-excitable blue fluorescent CF®350 dye has excitation/emission at 347/448 nm. • Blue fluorescent CF®405S dye has excitation/emission at 404/431 nm. • Blue fluorescent CF®405M dye has excitation/emission at 408/452 nm. • Green fluorescent CF®488A dye has excitation/emission at 490/515 nm. • Orange-red fluorescent CF®555 dye has excitation/emission at 555/565 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®633 dye has excitation/emission at 630/650 nm. • Orange-red fluorescent CF®555 dye has excitation/emission at 555/565 nm. • Far-red fluorescent CF®647 dye has excitation/emission at 650/665 nm. • Far-red fluorescent CF®660C dye has excitation/emission at 667/685 nm. • Far-red/near-IR fluorescent CF®680 dye has excitation/emission at 681/698 nm. • Near-infrared fluorescent CF®750 dye has excitation/emission at 755/777 nm. • Near-infrared fluorescent CF®770 dye has excitation/emission at 770/797 nm. • Far-red fluorescent CF®660R dye has excitation/emission at 663/682 nm. • Far-red fluorescent CF®640R dye has excitation/emission at 642/662 nm. • 405 nm-excitable green fluorescent CF®405L dye has excitation/emission at 395/545 nm.
