Detection of Caspr2-antibodies by immunofluorescence. Legend: Presence of Caspr2 antibodies was determined by a cell-based immunofluorescence assay. Patient’s serum sample was added to fixed cells that express Caspr2 protein on their surface (left) as well as to non-transfected cells (right). Reactivity at a serum dilution of ≥ 1:100 proves Caspr2 antibodies. The immunofluorescence pattern is shown at a magnification of 10 x (above) and 20 x (below)
