Assessment of MAR autoantibody capture, specificity, and affinity in vitro. (A) SNAREs captured up to 2.7 μg LDH B Ab/ mg SNAREs (95% efficiency) and exhibited increased antibody entrapment at higher concentrations. (B) SNAREs reduced LDH B antibody titer in human serum by as much as 90% (patient-derived serum of mothers of children with ASD). Scrambled peptide-DIONPs and DIONPs were used as negative controls. (C) Avidity of SNAREs to MAR LDH B antibody indicating a 50% avidity index at ~3.6 M sodium thiocyanate concentration.
