High-Resolution Cryo-EM Structure of TGR5 for Structure-Based Drug Design (SBDD)

We successfully determined the high-resolution cryo-EM structure of the Gs-coupled receptor TGR5 bound to the small molecule agonist P395, achieving an impressive resolution of 2.5 Å—surpassing previously published structures (e.g., PDB: 7CFM). This result highlights our advanced capabilities in resolving fine molecular details critical for understanding receptor-ligand interactions. 

This achievement demonstrates the effectiveness and quality of our cryo-EM services, providing a strong foundation for structure-based drug design (SBDD). Our team consistently delivers reliable, publication-ready structures that accelerate drug discovery.
