Antibody drugs have emerged as a vital class of therapeutics due to their ability to specifically target disease-related biomarkers. Understanding the binding activity of these antibody drugs is paramount in determining their therapeutic efficacy. The binding activity of an antibody drug is usually confirmed by rigorous affinity testing. This forms an important part of the antibody drug evaluation system. Creative Proteomics' customized antibody drug binding activity assay services provide important information on the interaction between an antibody drug and its target antigen, thereby optimizing drug discovery, development and subsequent therapeutic applications.
What is an Antibody Drug Binding Activity Test?
Antibody-receptor binding is crucial for antibody drugs, affecting their functional effects and inducing corresponding immune responses in the body. Antibody drug binding activity testing service is designed to help researchers and pharmaceutical companies assess the binding affinity and potency of their antibody drugs. By accurately measuring the binding activity of antibodies, we provide valuable information about their effectiveness, specificity, and potential therapeutic applications.

Binding Activity Testing Services at Creative Proteomics
Antibody drug efficacy depends not only on the binding activity of the Fab region to the target antigen, but also on the interaction of the Fc region with the Fc receptor. This interaction affects the half-life of the antibody drug and mediates antibody-dependent ADCC, ADCP and CDC effects. At Creative Proteomics, we use in vitro assays of antibody drug-receptor binding to predict the efficacy of antibody drugs. Our services include, but are not limited to, the following:
At our state-of-the-art facility, we employ various techniques, such as surface plasmon resonance (SPR), enzyme-linked immunosorbent assay (ELISA), and flow cytometry, to evaluate the binding activity of antibody drugs against specific targets. These methods allow us to determine the binding kinetics, affinity constants, and epitope specificity of the antibodies with high precision and sensitivity.
Our team of experienced scientists and experts works closely with clients to understand their specific needs and objectives. We offer customizable assays to accommodate different sample types. Whether it is characterizing monoclonal antibodies, polyclonal antibodies, or antibody-drug conjugates (ADCs), our comprehensive binding activity measurement service provides reliable and robust data to support antibody drug development.
