Technology

• Allows a single DNA sequence containing a chemical "handle" to be modified to attach one of a library of fluorescent labels to the DNA.
• Adaptable to other polymer backbones (RNA, protein, synthetic polymers, etc.)
• Fluorescent labels cover the visible region into the near-IR, with high absorbance and good quantum yield.

Applications and Advantages

• A single master sample of DNA can be modified to contain one of the library of fluorescent labels without the need to optimize any new synthesis reactions.
• Allows tuning of fluorescent dyes to specific wavelengths, e.g. for confocal microscopy.
• Fluorescent labels can report on aptamer binding, protein binding, DNA hybridization, polymer crosslinking, etc. via FRET, donor-quencher interactions, or other means.
• Avoids failure risk of adapting an existing polymer-based research tool to a new fluorescent labelling reaction.
• Only the handle is present during polymer synthesis, allowing post-synthetic attachment of fluorescent labels that would otherwise be incompatible with polymer synthesis conditions.
