Utilization of a multiple antigenic peptide as a calibration standard in the BAN50 single antibody sandwich ELISA for Aβ oligomers

► We have developed a calibration standard for the BAN50 ELISA for Aβ oligomers. ► A 16-mer multiple antigenic peptide (MAP) gave stable signals in the BAN50 ELISA. ► The standard curve covered the required range for signals from biological samples. ► A similar approach could provide a calibration standard for other oligomer ELISAs.
