Biologics Characterization

Structure, activity and potency of biologic drugs are critical quality attributes that need to be well characterized and monitored in the drug discovery process to reduce risk in drug development. At BOC Sciences, decades of scientific expertise and advanced technologies enable us to meet your development and manufacturing needs, and we offer a full suite of chemical-based analytical testing services to ensure the properties of your compounds and products are well characterized. Our biologics characterization solutions support the workflow from drug discovery to downstream characterization of biologics. BOC Sciences has the experienced staff and modern equipment to work on any kind of biologic drug product, including proteins, peptides, monoclonal antibodies (mAbs), bispecific antibodies, and antibody-drug conjugates (ADCs). Our team of scientists have employed a rational and scientifically driven approach based on the physicochemical and biophysical behavior of compounds to develop bioanalytical strategies and rapidly evaluate relevant properties. Formulations are designed, characterized and evaluated for their expected performance based on the intended route of administration and indication.
