Incorporation into DNA/cDNA by
- Nick Translation with DNAse I/ DNA Polymerase I  & in-house data
- Primer Extension with Klenow fragment 
Biotin-14-dATP is enzymatically incorporated into DNA/cDNA as substitute for its natural counterpart dATP. The resulting Biotin-labeled DNA/cDNA probes are subsequently detected using streptavidin conjugated with horseradish peroxidase (HRP), alkaline phosphatase (AP), a fluorescent dye or agarose/magnetic beads. Optimal substrate properties for Nick Translation are ensured by a 14-atom linker attached to the N6 position of adenine. For PCR incorporation experiments e.g. with Taq polymerase Biotin-11-dATP (#NU-1175-BIOX) is recommended whose Biotin moiety is attached to the N7-Deaza position of adenine via a 11-atom linker.
Recommended Biotin-14-dATP/dATP ratio for Nick Translation: 50% Biotin-14-dATP/ 50% dATP
Please note: The optimal final concentration of Biotin-14-dATP may very depending on the application and assay conditions. For optimal product yields and high incorporation rates an individual optimization of the Biotin-14-dATP/dATP ratio is recommended.
