Illustrated are three potentially functional dimer sites with interval distances of 80, 71, and 64 Ångströms between the interlayer MOG epitopes NLHRT and KTGQF, LHRTF and KTGQF, and HRTFE and KTGQF. Dimeric IgE complexing hinges upon disruption of the overhanging oligodendrocyte membrane surface and facilitated intracellular antibody inflow. For serum antibody immunoassay purposes, the longer, inclusive peptide NLHRTFE can be used together with KTGQF as both peptides are sufficiently hydrophilic when coupled with the peptide-solubilizing, amino-ADOOA-ADOOA linker.
