Antibody Humanization
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.
Technology platform
Antibody sequencing, structural biology analysis, phage display system, cell display system, protein expression purification system, Biacore/Fortebio test platform, stable cell line construction.
Overall Solutions
- IgG: CD BioSciences uses cell surface display technology to obtain humanized IgG antibodies by constructing and screening humanized IgG antibody mutation libraries.
- Small-molecule antibodies: CD BioSciences uses phage display technology to display humanized antibody mutation libraries on the surface of phage, and screen to obtain high-affinity and high-specificity humanized small-molecule antibodies.
Our Advantages
✓ Project experience: A number of antibody humanization and affinity maturation projects have been completed, and many modified antibodies are already in the clinical research stage.
✓ Humanization of antibodies from multiple species: including dogs, monkeys, mice, camels, alpacas, chickens, etc.
✓ Using the means of bioinformatics and structural biology, computer-aided design of antibody modification.
✓ The degree of humanization is relatively high. After the transformation, after the affinity maturation process, the affinity can reach nM and pM levels.
✓ Various humanization methods: chimeric antibody, CDR grafting, SDR grafting, chain replacement.
