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.

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.
Antibody Selection and Screening
Bioinformatics Analysis: Utilizing advanced bioinformatics tools to analyze antibody sequences, predict antigen binding sites, and assess potential off-target effects. We employe computational modeling and simulation techniques to design novel antibody variants with optimized binding properties.
Drug Conjugation Strategy
Conjugation Site Prediction: Predicting optimal sites for drug conjugation on antibody molecules to maximize drug loading and therapeutic efficacy.
Linker Design: Designing and evaluating linker molecules for efficient and stable drug release within target cells.
In Vitro and In Vivo Validation
Cell-Based Assays: Conducting in vitro assays to evaluate the binding specificity, internalization, and cytotoxicity of ADCs using cancer cell lines.
Animal Model Studies: Performing in vivo studies in animal models to assess the pharmacokinetics, safety profile, and therapeutic efficacy of lead ADC candidates.
