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.
- Format: OmpA leader sequence-Z-affibody
- Diversity: 4.8×1011
- The diversity and in-frame of the library was checked by NGS.
Fusion BioLabs Z-format Affibody combinatorial ready-to-panning phage library was constructed by saturation mutagenesis of the Z domain with random amino acid residues at positions 9, 10, 11, 13, 14, 17, 18, 24, 25, 27, 28, 32 and 35.
