Antibody Affinity Maturation Service (ONLY available in China temporarily)

Antibody Affinity Maturation Service Description

To achieve a certain level of therapeutic effect in vivo, the affinity of the antibody needs to reach a certain level. However, in some cases, it may not be easy to screen out antibodies that have both the correct biological function and high antigen-binding affinity. In this case, improving the antigen-binding affinity of existing antibodies may be the best way to introduce antibodies into drug development. In addition, the affinity of an antibody decreased obviously after humanization. Therefore, it is necessary to increase the affinity of humanized antibodies to the pre-humanized level. Affinity maturation is a common strategy to improve antigen-binding affinity of antibodies. Sino Biological Inc. offers antibody affinity maturation service that can improve the affinity of antibodies to a desired level.
