Characterization

ReadCrystal’s biophysical detection platform can provide comprehensive detection methods for the detection of protein-protein, protein-small molecules, protein-nucleic acid, and other molecular interactions. This platform is used to validate the affinity and stability between candidate small molecules and target proteins, optimize the safety and effectiveness of drugs, and promote the confirmation of lead compounds.
