What is protein labeling? Biological research often requires the use of molecular labels that are covalently attached to a protein of interest to facilitate detection or purification of the labeled …

We focus on advances in live‐cell labeling strategies and fluorescent probes, especially the HaloTag, SNAP‐tag, TMP‐tag, and unnatural amino acid systems and their applications.

Protein labeling technologies offer an alternative to fluorescent proteins for studying the function of proteins in living and fixed cells.

We demonstrated that the labeling of these encoded unnatural amino acids 1 – 3 is specific with respect to the entire soluble E. coli proteome and several orders of magnitude faster than …

Aug 1, 2025 · Site-specific protein labeling plays important roles in drug discovery and illuminating biological processes at the molecular level. However, it is challenging to label proteins with …

Protein labeling involves attaching tags, such as fluorescent dyes or biotin, to proteins to study their behavior, location, or interactions. It’s essential for cell imaging, quantitative proteomics, …

Explore the various protein labeling techniques including chemical, enzymatic, genetic, and isotopic methods. Learn about their applications, mechanisms, and optimization tips.

Protein labeling is the process of attaching detectable tags to proteins. These tags, including biotin, enzymes, fluorophores and radioactive isotopes, allow researchers to track and analyze …
