Antibody Design/Humanization Service

The non-human antibodies entering the human body can cause severe rejection. For example, the entry of murine monoclonal antibodies into the human body will cause the human anti-mouse antibody response (HAMA response), which will affect the clinical application of antibodies and severely impair the safety and treatment effect. Antibody humanization is the process of genetic engineering and recombinant expression of animal-derived antibodies so that most or all of the antibody's sequence becomes human-derived, ensuring antibody affinity and specificity and minimizing the heterogeneity of antibodies to humans.

Method

The current common computational antibody design method starts with the modeling of antibody and antibody-antigen complexes. Select antibody sequences for antigen binding experiments, for example, bind to soluble antigens or cell-expressed antigens, and further optimize the conjugate through affinity maturation methods. However, this type of method often requires modeling of the overall structure, which requires a large amount of calculations and takes a long time. Therefore, an antibody design based on the CDR of the specific binding site of the antibody and the antigen was proposed. This method simplifies the calculation and design of the antibody to the modeling and design of the antibody CDR, which greatly reduces the computational requirements.
