Antibody Affinity Maturation

Antibodies are widely used in the diagnosis and treatment of various diseases. Affinity maturation is the process of manipulating the variable regions of antibodies that have undergone somatic hypermutation to introduce point mutations in the framework and CDR loops to select variants with improved binding affinity for their target. Achieving high-affinity binding is essential to amplify the dissociation half-life, expand the detection limit, reduce the drug dose, and improve the efficacy of the drug. However, in vivo antibody affinity maturation usually fails to produce antibody drugs with targeted efficacy. Therefore, it is necessary to carry out further affinity maturation in vitro through directed evolution. CD BioSciences has established a comprehensive antibody design platform. We provide high-quality Antibody affinity maturation services based on our advanced platform, and we will do our best to promote the success of your project.

Overall Solutions

In CD BioSciences, phage and yeast surface display platforms are used for different antibody affinity maturation methods, and then high-throughput (HT) screening is performed to improve target binding affinity.

1. CDR randomization of different Ab fragment scaffolds (scFv, Fab, VHH).

2. Large single or large combination variable heavy/light chain yeast or phage display CDR libraries can be generated.

3. Multiple rounds of panning selections with increasing stringency can be performed in order to achieve demanding affinity improvements CD BioSciences can generate light chain shuffled antibody libraries by amplifying the VL library of B cells from human donors, including yeast or phage display libraries.
