Applications:
Incorporation into DNA/cDNA by
- PCR with Taq polymerase ^{in-house data}
- Nick Translation with DNAse I/ DNA Polymerase I ^[1,2]

- Reverse Transcription with MMLV Reverse Transcriptase ^[5]

Description:
Biotin-16-dCTP is enzymatically incorporated into DNA/cDNA as substitute for its natural counterpart dCTP. 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 and thus labeling efficiency as well as an efficient detection of the Biotin moiety is ensured by a 16-atom linker attached to the C5 position of cytidine.

Recommended Biotin-16-dCTP/dCTP ratio for PCR: 50% Biotin-16-dCTP/ 50% dCTP

Please note: The optimal final concentration of Biotin-16-dCTP may very depending on the application and assay conditions. For optimal product yields and high incorporation rates an individual optimization of the Biotin-16-dCTP/dTTP ratio is recommended.
