“We are pleased with the antibody humanization service and the purification service of GenScript ProBio. It is very impressive and professional. we validated the humanization service by testing the antibody against anti-human IgG as the secondary antibody. The humanized antibody purification met our expectations and need. The characterization of the antibody that was highlighted by the COA is excellent. We would continue to avail your service and will also recommend it to anyone who needs such service. Thanks.” – Govind Panchamoorthy, Director, Genus Oncology
Immunogenicity can potentially lead to reduced efficacy through rapid clearance or neutralization of the drug, or toxicity due to cross-reaction with proteins in the body, which can have catastrophic consequences for the patient. Antibody humanization can reduce the immunogenicity of monoclonal antibodies derived from xenogeneic sources and to improve their activation of the human immune system by replacing non-human antibody frameworks with human ones. It is a very important step in therapeutic antibody discovery process.
In some cases that the obtained leads have relative low affinity (such as phage library campaign), or the final application needs extremely high affinity, affinity maturation is required to preserve the epitope specificity and functional activity of the antibody and boost potency to the desired level. In addition, it can be useful to remove potential modification sites for improved developability.
As a one-stop supplier for therapeutic antibody discovery and development, GenScript ProBio is proud to offer integrated antibody humanization and affinity maturation service. Combining in silico CDR-grafting, structure-based back mutation, and, supported by our patented FASEBA(Fast Screening for Expression, Biophysical-properties and Affinity) screening, Biacore Surface Plasmon Resonance platform and functional assay platform, the antibody humanization service is offered at GenScript ProBio to generate humanized antibody maintaining the affinity and specificity of parental antibody and optimized activity, productivity and thermostability. Seamlessly integrated with humanization, the affinity maturation service will continuously improve the affinity by 10 to 50 folds.
