Biophysical Characterization

ReadCrystal’s biophysical detection platform offers comprehensive methods for the detection of protein-protein, protein-small molecule, 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 drug safety and efficacy, and promote lead compound confirmation.
