Figure 2: Photomicrographs shows C3 staining, (a) C3 mesangial staining, (b) granular (arrow) staining along glomerular capillaries in membranous glomerulonephritis (GN), (c) coarse mesangial (2+) focal extending to capillaries in dense deposit disease, (d) peripheral glomerular capillaries as seen in C3 GN, (e) C1q staining glomerular capillaries which is segmentally negative, (f) C1q along tubular basement membrane (fluorescein isothiocyanate [a, c-f: ×20, b: ×40])
