Antibody Humanization Service

KMD Bioscience has built up a mature antibody production platform with our well-established antibody engineering technology. With the booming development of antibody-based therapeutics, the demand for humanized antibodies is growing in parallel. 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 is used to reduce the immunogenicity of animal monoclonal antibodies and improve their activities in the human immune system. It is a very critical step in therapeutic antibody discovery process.

With our well-established antibody engineering platform, KMD Bioscience can offer efficient, and accurate antibody humanization service to the scientific community. We have developed antibody humanization strategies based on our phage display technology, which can maintain the specificity and affinity of antibodies to antigens, while significantly or completely eliminating the immunogenicity of antibodies in humans. KMD Bioscience provides multiple strategies, such as human framework selection, CDR (Complementarity-determining regions) back mutation library screening, etc. Meanwhile, we are devoted to providing comprehensive technical services, including protein expression, antibody production, antibody purification, affinity analysis, and antibody affinity maturation.


Service Process:



Service Content:


KMD Bioscience can provide three antibody humanization strategies:

CDR-Grafting Antibodies: This process involves transferring the antibody CDRs into a proper human antibody framework, while retaining their original affinity and specificity. Such as grafting of the murine CDRs into human frameworks.

Chimeric Antibodies: The creation of chimeric antibodies (non-human variable regions with human constant regions) can partially alleviate immunogenic response. They were transfected to mammalian cells for recombinant antibody expression using DNA recombination technology.

Fully Humanized Antibodies: Using gene editing technology, the antibody gene in animal somatic cells were replaced by human antibody gene, and the humanized antibodies was produced directly after animal immunization.



Service Highlights:


--Extensive experience in antibody engineering development
