Immunogen/Epitope

immunogern = Aβ oligomers (amyloid β-derived diffusible ligands, ADDLs), mixed with Freund's adjuvant (we suggest that the NU-1 and NU-4 epitope is three-dimensional, in which aggregation of Aβ1–28 to form a dimer is necessary to align correct amino acids in the binding pocket, perhaps several from each single peptide)

Specificity

The species recognized by NU-4 in western blots included lower order and prominent higher order oligomers (12–24mers). Aβ1–40 monomer was not recognized in immunoblots by NU-4. NU-4 binds strongly to Alzheimer's disease brain samples but not to control brain samples
