WebClassically, probes were radioactively labeled, often with 32P because of its high energy and ease of incorporation into the phosphate groups of dNTPs. Radioactively labeled probes are detected using X-ray film. Disadvantages of 32P: • Short half life (about 2 weeks) means probes must be used immediately, and the WebWith the radioactive method, all of the ddNTPs had the same radioactive label and needed to be used in separate reactions. The chief advantage of using fluorescence is that each dideoxynucleotide fragment has a different label and can be combined into a single reaction. greenville traffic ticket payment online
