Abstract:
Anti-cN1A autoantibodies are helpful for diagnosing inclusion body myositis (IBM). We have developed an immunofluorescence assay based on the perinuclear accumulation of GFP-cN1A. The analysis of patient sera indicated that this assay shows a higher sensitivity for anti-cN1A in IBM compared to alternative assays, without loss of specificity.
