Drug molecules and protein labeling

Protein labeling is a technique that combines markers with target proteins through in vivo or in vitro methods. The labeled protein still maintains protein activity, and the marker can serve as a tracer to indicate protein related reactions, as well as an intervention to target proteins or cells. With the development of technology in recent years, especially the discovery and application of green fluorescent protein (GFP), protein labeling technology is playing an increasingly important role in the field of life sciences.
