Tool Proteins

Tool proteins are functional proteins widely used in biomedical research for detection, purification, labeling, and signal amplification; they are not research targets themselves but play a key role as auxiliary tools in experimental systems. By virtue of their high-affinity binding properties, enzymatic activity, or tag-recognition ability, they provide stable and reliable technical support for experiments such as protein interaction analysis, immunoassays, and protein purification, constituting an important basic tool in modern life science research.
