Antibody Reformatting & Production

In addition to changing the Fc part of antibodies, the variable regions of immunoglobulins can also be reformatted into various fragments, such as Fab, F(ab)'2, scFv, VHH, and small antibodies, or can be combined to produce bispecific the second specificity of sex antibodies. Smaller antibody formats can be used to improve tumor/tissue permeability and relative ease of expression in non-mammalian systems. As a leader in antibody engineering, CD BioSciences can provide comprehensive antibody reformatting services.

Overall solution

▪ CD BioSciences can reformat antibody variable region genes (VH and VL) from a given antibody to encode different constant regions, including Fab.

▪ CD BioSciences can use a variety of species and isotypes, and can choose to synthesize constant regions. These expression constructs are transfected into HEK293 cells and then subjected to protein A purification or other selected affinity-based chromatography.

▪ Based on our comprehensive structure-based antibody reformatting service, new antibodies can be designed and engineered into scFv and VHH. CD BioSciences customize services according to customers' specific requirements. We also provide other epitope-specific antibody design services.

Our features

▪ Our antibody reformatting & production service can improve pharmacokinetics: isoelectric point engineering and engineering PH dependence.

▪ Our antibody reformatting & production service can improve drug properties: improve thermal stability, improve solubility, improve chemical stability and improve heterogeneity.

▪ Our antibody reformatting & production service can reduce immunogenicity.

Our advantages

▪ CD BioSciences' services are tailored to each project to ensure that goals are met or exceeded.

▪ CD BioSciences' experienced project team will be assigned to each study, focusing on completing the progress of the project in the shortest possible time.

▪ Our customers widely regard us as a professional and attentive partner that provides quality results.
