Area of Science:

  • Biotechnology
  • Molecular Biology
  • Immunology

Background:

  • Phage display has been utilized for nearly 15 years for selecting specific antigen-binders.
  • Filamentous phages express foreign proteins on their surface while carrying the genetic information internally.
  • This ensures a stable link between the expressed protein (phenotype) and its genetic code (genotype) throughout selection and amplification.

Purpose of the Study:

  • To review the fundamental principles of antibody phage display technology.
  • To discuss recent advancements and applications in the field.
  • To highlight its significance in developing novel therapeutics.

Main Methods:

  • Utilizing artificial libraries of single chain antibodies.
  • Employing filamentous phages for surface protein expression.
