Cell-based assay by immunofluorescence cytochemistry (CBA-IFC) has been shown to be the most accurate method to detect anti-aquaporin (AQP) 4 autoantibodies. Detection of anti-AQP5 autoantibodies is delicate, which depends on the proper expression of AQP5 on the plasma membrane. Here, we describe methods to determine anti-AQP5 autoantibodies by CBA-IFC. Both anti-AQP5 IgG and IgA can be detected by this method.
