Small Molecules


The determination of the affinity of a small molecule binding to a therapeutic target is a significant component of drug discovery and lead optimization. The Octet® RED and Octet HTX systems are designed with rapid data acquisition and sensitivity to enable the detection of small molecules and peptides in a simple, user-friendly workflow in conjunction with Super Streptavidin biosensors. Label-free analysis of the association and dissociation of a small molecule with the target protein of interest results in the determination of kinetic constants including the association rate constant (ka), dissociation rate constant (kd), and equilibrium dissociation constant (KD).
