From: Two new cases of anti-Ca (anti-ARHGAP26/GRAF) autoantibody-associated cerebellar ataxia
Preadsorption of the patients’ sera with recombinant human full-length ARHGAP26 but not preadsorption with a control protein resulted in complete disappearance of the typical anti-Ca cerebellar staining pattern as detected by IIF (left panel: binding of serum IgG from patient 1 to a cerebellum tissue section before preadsorption with ARHGAP26, right panel: after preadsorption with ARHGAP26).
