Premade Phage Display Antibody Library Screening Introduction

Phage display technology is a highly efficient gene expression screening technology, in which exogenous proteins or peptides are fused with specific phage coat proteins, displayed on the phage surface and maintain relatively independent spatial conformation and biological activity, which is conducive to the specific recognition and binding of target molecules, thus realizing the unity of the genotype and the expression phenotype. It combines the selective ability with the amplification ability, has a powerful screening ability, can simulate the antibody generation process in vivo and in vitro, and can prepare and produce monoclonal antibodies without going through the hybridoma pathway or even without immunization. This is of great significance for the development and exploitation of antibodies. At present, phage display technology is widely used in the research and development of antibodies worldwide. Based on our rich field experience and advanced research platform, Creative Biolabs provides comprehensive services to support premade antibody library screening.

Premade Phage Display Antibody Library

Phage antibody library technology is a widely used technology for the preparation of genetic engineering antibodies. It has important theoretical and practical value in the cloning of human antibodies, the modification of antibody properties, and the study of antibody genes. The screening ability of antibody library display technology lays the foundation for its application and development. However, whether the expected antibodies can be obtained from the antibody library is restricted by many factors, including the storage capacity, diversity, storage conditions, amplification and screening procedures, etc. The screening strategy needs to be determined according to the nature of the antigen.

Current types of premade phage display antibody libraries include, but are not limited to, premade human and mouse antibody libraries, premade single domain antibody libraries, and immunized human antibody libraries. These antibody libraries are essentially derived from plasma cells from a large number of healthy or patient donors. They can be widely used for functional human antibody discovery, anti-peptide/protein antibody discovery, bifunctional antibody discovery, anti-epitope antibody discovery, and so on. This is of profound significance for antibody research and therapeutic antibody discovery.

Premade Phage Display Antibody Library Screening

Screening of phage antibody libraries is a critical step in phage display. Determining the appropriate screening method is crucial for the results of phage display. Common screening methods for phage antibody libraries include classical screening methods and novel screening methods. Generally, classical screening methods include solid-phase screening and liquid-phase screening. These two methods are mainly used for antibody discovery with a clear antigen. And for cases where the nature of the antigen is unclear or the antigen cannot be purified, new screening methods are needed to establish phage-displayed antibody libraries. Currently, cell-based screening, protein chip screening, etc. In specific studies, different screening methods need to be compared for different experimental programs and research purposes to determine the most appropriate screening technique.
