Antibody Phage Display Library Panning Services
Phage display is a laboratory technique that uses bacteriophages to associate proteins with their respective genetic information for studying protein–protein, protein–peptide, and protein–DNA interactions. The antibody phage display technique is based on genetic engineering of bacteriophages and repeated rounds of antigen-guided selection and phage propagation. It allows in vitro selection and production of recombinant monoclonal antibodies of high specificity and affinity.
Phage display-derived monoclonal antibodies have revolutionized drug discovery and represent an alternative technique to the traditional hybridoma technology. Fusion Biolabs scientists have applied this technology to develop antibodies for therapeutic or diagnostic antibody applications.
Fusion Biolabs has a wide range of ready-to-panning antibody phage libraries, including non-immune libraries, such as naive antibody phage library or synthetic antibody phage libraries, and immune antibody libraries from immunized animals or patients. Those ready-to-panning antibody phage libraries present various formats, such as scFv, Fab, VHH and affibody, to make it convenient for different target panning and for a variety of applications.
Our antibody phage display panning services allow the selection (“panning”) of recombinant antibody fragments from antibody gene libraries and screening of individually selected antibody clones with high specificity and affinity.
Fusion Biolabs have different types and formats ready-to-panning phage libraries for your targets panning.

2. Peptide Phage Display Libraries (Cyclized C8C and linearized X8, X16 and X24 peptide phage display libraries)
Fusion Biolabs peptide phage display system is based on a simple M13 phage vector as N-terminal fusions to the minor coat protein pIII. The peptide phage display libraries have been used for various applications, including epitope mapping, anti-microbial/viral peptides, material-specific peptides, bioactive peptides, small molecule binders, cell targeting peptides and novel enzyme substrates discovery through in vitro and in vivo panning approaches.

3. Affibody ready-to-panning phage display library
Affibody molecules are a class of small robust scaffold proteins derived from the IgG binding domain of Staphylococcus aureus protein A (SPA). Thirteen specific amino acids in the three α-helix regions of the IgG binding domain can be randomly mutated to construct an affibody library. This library can be screened to obtain affibody molecules with high affinity and specificity to any given target molecule.
