Perinuclear anti-neutrophil cytoplasmic antibodies (p-ANCA, MPO-ANCA, anti-MPO, ANCA-P) display a perinuclear staining pattern and are known to be common targets for myeloperoxidase (MPO). MPO is a neutrophil granule protein which has a primary function during normal metabolic processes in order to generate oxygen radicals. However, the proportion of pANCA sera with anti-MPO antibodies has only been reported in as low as 12% of patients with vasculitis condition. p-ANCA is associated with a number of medical conditions such as rheumatoid arthritis, primary sclerosing cholangitis, ulcerative colitis, eosinophilic granulomatosis with polyangiitis, microscopic polyangiitis, crescentic glomerulonephritis and focal necrotising. The analysis of anti-PR3 and anti-MPO levels has been found to correlate with the clinical status and both of these are at elevated levels in active disease and the antibody titres start to decrease during therapy, eventually becoming undetectable after remission. The classical methods for the measuring ANCA are ELISA and immunofluorescence tests and using these methods has identified two main patterns a cytoplasmic (cANCA) and a perinuclear (pANCA) type.
Human ANCA-P ELISA kit is a procedure designed for detecting IgG autoantibodies to myeloperoxidase (MPO) using human plasma and serum. This assay has a minimum analytical sensitivity limit of 0.5 U/ml.
The minimum detection sensitivity level of human IgG autoantibodies to myeloperoxidase (anti-MPO) using this human ANCA-P ELISA kit was 0.5 U/ml. The dynamic assay range for this kit is 5 – 100.0 U/ml.
