Humanized Non-IgG Antibodies Engineering Service

More Info

With years of experience and high-end technologies in antibody engineering, Creative Biolabs has successfully developed a series of innovative and diversified antibody platforms to provide fast and convenient non-IgG antibodies (IgM, IgE or IgA) humanization services for our worldwide customers.

Antibody Humanization

Antibodies have become an effective tool in various human diseases treatment and diagnosis, and they play an essential role in the remarkable progress of antibodies as therapeutic molecules. Antibody humanization is necessary and of great significance when these therapeutic monoclonal antibodies are produced from non-human systems. It can decrease the immunogenicity, improve its pharmacokinetics in vivo, and maintain high affinity and specificity of monoclonal antibodies (mAbs) by antibody humanization engineering.

Heretofore, different methods and techniques have been developed for the humanization of non-human antibodies to improve their biological properties. Currently, antibody humanization can be conducted by several engineering techniques, such as complementarity determining the region (CDR) grafting, chain shuffling, resurfacing and antibody library selections.

With the development of research on bioactive molecules, not only IgG mAbs but also non-IgG antibodies play an increasingly important role in the diagnosis and treatment of diseases. It is necessary to develop humanization engineering techniques for non-IgG therapeutic antibodies. At Creative Biolabs, high-quality non-IgG antibodies (mainly IgA, IgM, and IgE) are generated by our Expression System Platform through DNA recombinant technologies. For non-IgG therapeutic antibodies that are obtained from non-human expression systems, we optimize them through humanization engineering technique to enhance their performance.

Antibody Humanization Services at Creative Biolabs

Humanization of non-IgG antibodies usually conducted via CDR grafting at the DNA level, meaning that inserting appropriate or designed CDR coding segments into a human antibody framework. Once your non-IgG antibody is obtained, scientists at Creative Biolabs can start with DNA sequence determination of your non-IgG antibodies CDRs and provide professional humanization services based on our advanced technology platform. Our humanized non-IgG antibodies services mainly include, but are not limited to:

  • Antibody humanization design
  • Vector synthesis and cloning
  • Transient expression
  • Stable expression of cell lines
