The binding of receptors and ligands in living cells is a prerequisite for multiple biological reactions and is of great significance for most biological processes in organisms. BOC Sciences has extensive experience in ligand binding detection, and can use a variety of advanced technology platforms to provide technical services for measurement. We always ensure the accuracy and repeatability of the detection results and meet customer needs for high-quality, high-efficiency and low-cost technical services.


Proteolysis targeting chimera (Protac®) is composed of two ligands and a linker. The specificity of these two ligands allows Protac® to bind to the target protein and recruit E3 ubiquitin ligase. The binding of the ligand to the target protein determines whether Protac® can accurately locate the target protein, and the binding between the ligand and the E3 ubiquitin ligase is closely related to the ubiquitin cascade, and affects subsequent protein degradation reactions. Measurement of ligand binding is helpful for ligand design and screening, so it is necessary to detect and analyze the binding of two ligands during Protac® development or optimization.
