Determining the three-dimensional (3D) structure of proteins is critical for understanding the mechanism of coronavirus infection, discovering potential drug targets and structure-based drug design. Rapid advances in methodologies for protein expression and purification have made it easy to obtain enough quantities of proteins for structural studies. In addition, many breakthroughs have been made in X-ray crystallography, nuclear magnetic resonance (NMR) spectroscopy, and electron microscopy (EM) techniques related to protein structure analysis. As a professional structural biology service supplier, Creative Biostructure can offer a range of services for the structure determination of viral structural proteins/non-structural proteins, host proteins, antigen-antibody complexes, etc., using our three established structural biology technology platforms.
