Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibodies consist of four polypeptide chains: two identical heavy...

  • To emphasize the design of humanizing antibody libraries and combinatorial scanning mutagenesis libraries.
  • To provide guidance on troubleshooting common issues in the phage display process.

Main Methods:

  • Utilizes phage display technology for protein and antibody engineering.
  • Involves library synthesis, selection of desired clones, and high-throughput screening.
  • Focuses on creating humanizing antibody libraries and combinatorial scanning mutagenesis libraries.

Main Results:

  • Phage display facilitates the isolation of proteins with enhanced affinity, specificity, and stability.
  • Enables engineering of proteins with novel enzymatic activities.
  • Provides a robust platform for rapid protein and antibody improvement.

Conclusions:

  • Phage display is an efficient and versatile platform for protein and antibody engineering.
