Dye-labeled phosphoramidites are intended for oligonucleotide synthesis designed for molecular assays, microscopy, and microarrays. A broad range of labeling options are available with coupling efficiency, emission, and absorption spectra comparable to other commercially available dyes.

Designed for oligonucleotide synthesis of diagnostic research and manufacturing development

These phosphoramidites may be used on automated DNA synthesizers following standard synthesis and deprotection procedures. Fluorescent tags can be incorporated at the 5′ end of an oligonucleotide.

Technical specifications for DyLight-labeled phosphoramidites
