Recently, we demonstrated the presence of naturally occurring antibodies against amyloid- β (nAbs-Aβ) within the pool of IVIG. In this study, we compared different brands of IVIG for nAbs-Aβ and have found differences in the specificity of the nAbs-Aβ towards Aβ1–40 and Aβ1–42 . We analyzed the influence of a pH-shift over the course of antibody storage using ELISA and investigated antibody dimerization at acidic and neutral pH as well as differences in the IgG subclass distributions among the IVIG using both HPLC and a nephelometric assay. Furthermore, we investigated the epitope region of purified nAbs-Aβ. The differences found in Aβ specificity are not directly proportionate to the binding nature of these antibodies when administered in vivo. This information, however, may serve as a guide when choosing the commercial source of IVIG for therapeutic applications in Alzheimer's disease Y1 - 2010 U6 - https://doi.org/10.3233/JAD-2010-1353 SN - 1387-2877 VL - 20 IS - 1 SP - 135 EP - 143 PB - IOS Press CY - Amsterdam ER - TY - JOUR A1 - Selmer, Thorsten A1 - Kim, Jihoe A1 - Darley, Daniel A1 - Buckel, Wolfgang T1 - Characterization of (R)-2-hydroxyisocaproate dehydrogenase and a family III coenzyme A transferase involved in reduction of L-leucine to isocaproate by Clostridium difficile / Kim, J. ; Darley, D. ; Selmer, T. ; Buckel, W.
