Binding curves of CSF samples from patients with NMDAR encephalitis. Normalized MFI signals (± SEM) show concentration-dependent binding of human CSF samples to NR1 protein (a). None of the binding curves reached their MFImax plateau, indicating that CSF NR1 antibody concentrations were clearly below the saturation of the NR1 epitopes and that the binding constant c50 cannot be calculated in these samples. The MFI did not correlate in this small patient cohort with patient age (b), modified Rankin scale at the time of CSF analysis (c) and the duration of the hospital stay (d)
