    Phage Display Technology

    Phage display technology is a molecular biology technology in which antibody genes are displayed on the surface of phage in the form of antibody-coat protein fusion protein. The antibody library constructed by this technology can obtain specific antibodies after enrichment, screening and identification, which has the advantages of simple method, short experimental period and large screening capacity. The phage antibody library technology platform launched by Clongene can provide you with multi-species and multi-type phage antibody library services according to your needs.

    Service advantages:

    • Rich experience: more than 3 years of phage antibody development experience

    • High capacity: natural antibody library 1010 and above, immune antibody library 107 and above

    • High success rate: screening success rate is greater than 90%

    • Multi-species: antibody libraries of human, mouse, rabbit and other species can be constructed

    • Multi-type: ScFv, Fab, VHH and other types of antibody libraries can be constructed
