Western blot analysis of human neutrophil lipocalin (HNL) and matrix metalloproteinase-9 (MMP-9) in serum. The result from two patients, among six with identical results, is presented. The left side shows the results of HNL blotting. Only homodimeric and heterodimeric forms of HNL were detected at molecular sizes of approximately 45 kDa and 110 kDa. The right side shows the results of MMP-9 blotting with the lower molecular size of MMP-9 coinciding with the position of HNL at approximately 110 kDa, in addition to a higher molecular band corresponding to approximately 200 kDa
