Description
PR3 sensitive is a solid phase enzyme immunoassay employing highly purified native human proteinase 3 (PR3) from human neutrophil granulocytes for the quantitative detection of antibodies against proteinase 3 in human serum. Anti-PR3 antibodies recognize specificially conformational epitopes only accessible on native PR3. The assay is an aid in the differential diagnosis of autoimmune vasculitis
