Can not only design humanized antibody but also construct a humanized antibody library.
It turned out to be a game changer in the way antibodies are generated.

Antibodies are the first proteins which were successfully displayed on the surface of phage by fusing the coding sequence of scfv or fab to the coat protein.
In summary antibodies with subnanomolar affinities can be selected from either type of library naïve or synthetic.
Nucleotides and amino acids are shown in lower and upper case respectively.
Because of their critical role in the antibody antigen interaction these six regions are the main target for randomization in most synthetic library designs.
Ylanthia comprises 36 fixed immunoglobulin ig variable heavy vh variable light vl chain pairs which cover a broad range of canonical complementarity determining region cdr structures.
This report describes the design generation and testing of ylanthia a fully synthetic human fab antibody library with 1 3e 11 clones.
The four diversified cdrs are delineated by boxes and the diversified positions are shaded gray.
If the assembly by cloning or pcr and preservation of molecular complexity is carefully controlled at every step of its construction high quality libraries of more than 10 10 independent clones can be generated with the potential to yield hundreds of different antibody.
It is the first fully synthetic fully human library ever developed.

Hanes et al 1998 which incorporates affinity maturation and directed evolution directly in the workflow the basic operation of both natural antibody generation and somatic mutation had been replicated in the laboratory.
This general methodology could be applied to generation of large functional synthetic antibody libraries using standard supplies equipment and molecular biology techniques.
Antibodies complementarity determining regions.
Antibody phage display library antibody libraries are constructed by the genomic information coding for antibody variable domains which can be derived from b cells of immune or naïve donors.
Effective humanized antibody can be observed only after several rounds of screening with highly efficient screening method.
A whole library can be completed within 12 weeks.
