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. 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
