Useful Approaches for Labeling Peptides with Fluorescent Dyes

In comparison to other imaging techniques, fluorescent imaging is particularly advantageous due to its high sensitivity, nonradioactive materials, and ability to be detected by low-cost instruments. Peptides that have fluorescent labeling can provide biological information at the molecular level in living systems, enable the visualization of molecular events occurring in disease processes, and monitor therapeutic effects. Given the increasing interest in the development of chemical tools for biological research, the importance of fluorescent peptides is expected to grow.
