Comprehensive identification of immune complex antigens (IC-antigens) in cerebrospinal fluid (CSF) is useful to provide insights into pathophysiology and could form the basis for novel diagnostic and treatment strategies for central nervous system autoimmune diseases and other neurological disorders. Immune complexome analysis is the method for comprehensively identifying IC-antigens in biological fluids (such as serum and CSF). Here, we describe IC-antigens detection method; specifically, ICs in CSF are captured and are subjected to papain-digestion elution and tryptic digestion, and are analyzed by nano-liquid chromatography-tandem mass spectrometry (nano-LC-MS/MS).
