This study introduces a new molecular design method by shuffling in vivo formed complementarity determining regions (CDR) into antibody framework regions. This approach generates diverse synthetic antibody gene libraries for novel therapeutic development.

Area of Science:

  • Molecular Biology
  • Immunology
  • Protein Engineering

Background:

  • Antibody engineering relies on precise design of complementarity determining regions (CDRs).
  • Generating diverse antibody libraries is crucial for discovering novel therapeutics.
  • Current methods for CDR randomization can be complex and limited in scope.

Purpose of the Study:

  • To develop a novel molecular design strategy for antibody engineering.
  • To create a diverse synthetic gene library of soluble VH-fragments.
  • To explore simultaneous randomization of CDR length, sequence, and combination.

Main Methods:

  • Shuffling in vivo formed CDRs from antibody genes into a specific framework region.
  • Construction and sequencing of a synthetic gene library of soluble VH-fragments.

  • Analysis of library complexity and diversity through sequencing.

    • Main Results:

    • A diverse synthetic gene library of soluble VH-fragments was successfully created.
    • The library contained random combinations of CDRs from different germlines.
    • Simultaneous randomization of CDR length, sequence, and combination was achieved in one step.

    Conclusions:

    • The presented approach offers a novel and efficient method for molecular design in antibody engineering.
    • This strategy enables the generation of highly diverse antibody libraries with varied CDRs.
    • The method holds potential for accelerating the discovery of new antibody-based therapeutics.
