Fluorescent tagging vs radioactively tagg
In molecular biology and biotechnology, a fluorescent tag, also known as a fluorescent label or fluorescent probe, is a molecule that is attached chemically to aid in the detection of a biomolecule such as a protein, antibody, or amino acid. Generally, fluorescent tagging, or labeling, uses a reactive derivative of a fluorescent molecule known as a fluorophore. The fluorophore selectively bind… 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
