Objective： To summarize the principle, building, screening and applications of phage antibody library technology, and thus to provide a reference for the anti-tumor antibody drug development. Methods： The principle, building, screening and applications of phage antibody library technology are reviewed based on experimental papers using phage antibody library technology in the recent five years. Results： Phage library is divided into two categories： immune antibody library and non-immune antibody library; the screening techniques include affinity screening, cell-based screening and in vivo screening; it is mainly used to identify tumor markers and for tumor diagnosis, screening and preparation of anti-tumor antibody drugs. Conclusion： Phage antibody library technology is convenient,fast, efficient and can be cultured in vitro environment, which determines its wide application in the discovery of tumor markers and anti-tumor antibody drug research and development. Currently, there are still some flaws in phage antibody library technology, but as the technology continues to evolve and be innovated, phage antibody library technology is bound to become a new way to research and develop antibody drugs, which will greatly promote the development of anti-tumor antibody drugs.
