Fluorescein-12-dCTP

• Catalog Number: orb533142
• Category: Tools
• Description: Fluorescein-12-dCTP 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 Fluorescein-12-dCTP/dCTP ratio for PCR and Nick Translation: 30-50% Fluorescein-12-dCTP-/70-50% dCTP.
