ADC Antibody Screening


ADC Antibody Screening

Antibody-Drug Conjugates (ADCs) represent a promising class of targeted therapies that combine the specificity of monoclonal antibodies with the cytotoxic potency of small molecule drugs. By precisely delivering cytotoxic agents to tumor cells while sparing healthy tissues, ADCs have emerged as a transformative approach in cancer treatment. However, the successful development of ADCs relies heavily on the identification of high-affinity antibodies that selectively target tumor antigens.

Introduction of ADC Antibody Screening

ADC Antibody Screening is the process of evaluating and selecting antibodies for their suitability to be used in Antibody-Drug Conjugates (ADCs), which are a class of targeted cancer therapies combining monoclonal antibodies with potent cytotoxic drugs. This screening process can be classified into criteria such as antibody specificity, internalization efficiency, binding affinity to the target antigen, stability, and low immunogenicity.
