Abstract:

Phage antibody display technology is the first and most widely used of the in vitro antibody screening technologies,which enable the discovery of human antibodies for therapeutic applications associated with all kinds of diseases. Different antibody discovery approaches exist,but phage antibody display technology has become an indispensable tool for the discovery and optimization of target-specific monoclonal antibodies. The researchers can create combinatorial antibody libraries on filamentous phage to be utilized for generating antigen specific antibodies in a matter of weeks. In the current situation of pandemic of Coronavirus disease(COVID-19),the research for neutralizing antibodies is motivating the researchers to find therapeutic candidates against SARS-CoV-2. By panning phage antibody libraries,many different SARS-CoV-2 neutralizing antibodies have been found at present. Therefore,we summarize the principles of phage antibody display technology,and the construction,classification and panning process of phage antibody library,also discuss the advantages and limitations. Furthermore,we summarize the recent advances in the use of this technology for discovering neutralizing antibody against SARS-CoV-2. It is aimed to provide the theoretical support for the application of this technology in antibody discovery in the coming years.

Key words: monoclonal antibody, phage antibody display, antibody library, panning, SARS-CoV-2
