2. Figure 1
Glomerular deposition of galactose-deficient IgA1 in patients with IgA nephropathy (IgAN). Double staining with anti-IgA polyclonal antibody and KM55 monoclonal antibody was performed on biopsy specimens from 48 patients with IgAN. Five clinical cases are shown. Galactose-deficient IgA1 was clearly localized predominantly in the mesangium with IgA C3. (Bars = 100 μm; original magnification X200.)

KM55 mAb staining. (a) KM55 mAb staining in various types of glomerular diseases. Glomerular galactose-deficient IgA1 staining was negative in cases of hepatitis C virus–related nephropathy (HCV-RN), hepatic glomerulosclerosis, idiopathic membranous nephropathy (MN), secondary MN, acute poststreptococcal glomerulonephritis (APSGN), antineutrophil cytoplasmic antibody (ANCA)–related nephropathy, and minimal change nephrotic syndrome (MCNS).(b) KM55 mAb staining in lupus nephritis. Five cases of lupus nephritis are shown as examples. In all cases of lupus nephritis that were accompanied by glomerular IgA deposition, glomerular galactose-deficient IgA1 staining was negative. (c) KM55 mAb staining in IgA vasculitis with nephritis (IgA-VN). Five cases of IgA-VN are shown as examples. All cases of IgA-VN exhibited glomerular galactose-deficient IgA1 staining, mainly in the mesangial area, as seen in cases of IgA nephropathy (IgAN). (Bars = 100 μm; original magnification X200.)
