Incorporation into DNA/cDNA by
- PCR with Taq polymerase in-house data
- Nick Translation with DNAse I/ DNA Polymerase I in-house data
5-Propargylamino-dCTP-Cy5 is recommended for direct enzymatic labeling of DNA/cDNA e.g. by PCR and Nick Translation. It is incorporated as substitute for its natural counterpart dCTP. The resulting Dye-labeled DNA/cDNA probes are ideally suited for fluorescence hybridization applications such as FISH or microarray-based gene expression profiling. Optimal substrate properties and thus labeling efficiency is ensured by an optimized linker attached to the C5 position of cytidine.
Recommended Propargylamino-dCTP-Cy5/dCTP ratio for PCR and Nick Translation: 30-50% Propargylamino-dCTP-Cy5/ 70-50% dCTP
Please note: Protect the Dye-labeled dCTP from exposure to light and carry out experimental procedures in low light conditions. The optimal final concentration of the Dye-labeled dCTP may very depending on the application and assay conditions. For optimal product yields and high incorporation rates an individual optimization of the Dye-labeled-dCTP/dCTP ratio is recommended.
