EXCYTE antibody humanization technology is based on bioinformatics and small-scale expression combination library to generate humanized sequence combinations with the highest “human” homology. These different humanized clones with various combinations are expressed in the mammalian cell expression system, and immediately available to be tested in binding ability and biological functions.

The EXCYTE antibody humanization design is free from the dependence on three-dimensional structure information. It combines the latest humanization design concepts, comprehensively considers the amino acids which may affect the structure and function of a given antibody CDR in the framework sequence, and strives for maximum humanization substitution. At the same time, based on the combination and selection, the EXCYTE humanization has the benefits of humanization in minimal impact of affinity, simultaneous optimization of the biophysical and biochemical properties of antibodies (expression, cohesion, stability, etc.) and easy transfer to downstream development of drug antibodies.

The small-scale expression combination library technology of EXCYTE will be able to simultaneously express hundreds of different gene sequences of antibodies, providing a sufficient number of purified samples to carry out physicochemical and biochemical experiments including flow cytometry, antibody affinity, aggregation tendency and concentration-dependent biological activity analysis, which make it easy to obtain the best candidate antibody clone quickly.
