• PubMed Abstract: 
  

Bapineuzumab (AAB-001) and its derivative (AAB-003) are humanized versions of the anti-Aβ murine antibody 3D6 and are immunotherapy candidates in Alzheimer's disease. The common Fab fragment of these immunotherapies has been expressed, purified and crystallized in complex with β-amyloid peptides (residues 1-8 and 1-28). Diffraction data at high resolution were acquired from crystals of Fab-Aβ8 (2.0 Å) and Fab-Aβ28 (2.2 Å) complexes at the Australian Synchrotron. Both crystal forms belonged to the primitive orthorhombic space group P21221.
