For nonradioactive DNA labeling such as random priming, PCR labeling, or nick translation.
- Biotin-16-dUTP is used as asubstrate for: Terminal Transferase
- DNA polymerase I (holoenzyme and Klenow fragment)
- Taq DNA polymerase
- Reverse transcriptase (e.g., Transcriptor)
Biotin-16-dUTP replaces dTTP in the random-primed DNA labeling reaction or in nick translation in a ratio of 35% Biotin-16-dUTP and 65% dTTP, as well as in PCR.
The nucleotide also serves as a substrate for Terminal Transferase in 3′-end labeling.
- Biotin-labeled DNA can be detected with: Streptavidin-alkaline phosphatase conjugate and a chemiluminescent substrate (CSPD, CDP-Star) or a color substrate
- Biotin Luminescence Detection Kit
