Cross-linking is a technique in which two or more biomolecules are covalently combined to form a conjugate with enhanced physical properties and/or biological functions. The structure of functional proteins involves not only intramolecular covalent bonds, which leads to challenging questions about the spatial direction and non-covalent interactions of proteins. In protein chemistry, cross-linking agents are widely used to study the interaction between molecules and to construct new structures. Mechanically, cross-linking strategies can be divided into three categories: chemical cross-linking, enzymatic cross-linking and photocrosslinking.


In recent years, chemical cross-linking has become an effective tool for the study of proteins and other biomolecules. It can be used in a variety of studies, including attaching proteins to solid supports to study membrane receptors, protein-protein complexes, protein-DNA complexes and so on. When combined with techniques such as mass spectrometry, it is used not only to determine the three-dimensional structure of proteins, but also to study protein-protein interactions and identify sites of interest.
