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… WebThe use of fluorescent tags is widespread in the studies of protein–nucleic acid interactions for imaging and structural/functional studies on both single-molecule …

Radioisotopes are used to measure the concentration of antigens or antibodies. Radioimmunoassay (RIA) Principle -Relies on the principle of competitive binding. WebFluorescent tags are used in various cell biology studies to determine localization of target proteins, protein dynamics and tracking, live cell imaging, and cell sorting. Use of Green Fluorescent Protein (GFP) and its family members as fluorescent tags have become routine for tracking cellular proteins.
