Application
Atto fluorescent labels are designed for high sensitivity applications, including single molecule detection. Atto labels have rigid structures that do not show any cis-trans-isomerization. Thus these labels display exceptional intensity with minimal spectral shift on conjugation.

Fluorescent-labeled DNA is generated through enzymatic incorporation of fluorophore-linked 2'-deoxyribonucleoside-5'-triphosphates (dNTPs) by DNA polymerases. We describe the synthesis of a variety of dye-labeled dNTPs. Amino-linker-modified 5'-triphosphates of all four naturally occurring nucleobases were used as precursors. Commercially available dyes were
