Biotin-14-dCTP is used for DNA biotinylation, an excellent, and sometimes superior alternative to conventional radioisotopic labeling. Advantages of using biotinylated DNA probes include:

• Convenience and safety—probe preparation generates no radioactive waste
• Stability—probes remain active longer than isotopically labeled probes
• Versatility—biotinylated DNA can be used for immobilization and capture procedures via streptavidin binding

About Biotin-14-dCTP
Biotin-14-dCTP is a patented dCTP analog with biotin attached at the N⁴-position of the pyrimidine base by a 14-atom linker. This nucleotide can be efficiently incorporated into DNA by nick translation in the presence of dATP, dGTP, and dTTP, labeling DNA with terminal deoxynucleotide transferase, or random primer synthesis. The amount of material provided is sufficient for labeling up to 50 μg of DNA.

Performance and quality testing
Purity is evaluated by reverse-phase HPLC.
