One of the primary objectives of molecular biology research is to identify the structure of proteins. Protein complex analysis requires a thorough research of proteins' structure and function because they are found in complicated biological samples. The structure of protein complexes can be ascertained using contemporary protein complex analysis methods. Many studies are currently being conducted employing cryo-electron microscopy (EM), small angle X-ray scattering (SAXS), nuclear magnetic resonance (NMR) spectroscopy, and X-ray crystallography to describe and understand molecular structures and molecular recognition mechanisms. Equipment for 3D protein structure analysis is available from reputable manufacturers including Bruker Corporation, JEOL Ltd., and Spectris plc depending on what is required. These tools can meet the laboratory's throughput requirements. In 2021, the global 3D protein structure analysis market was valued at $1,017.2 million, and it is expected...
