Figure 2: Immunofluorescence staining for NAPlr in tissue sample from a patient with acute poststreptococcal glomerulonephritis. Staining sites, which are thought to represent free antigen, are localized primarily in the mesangium and part of the glomerular basement membrane (GBM), and infiltrating leukocytes show a ring-like granular pattern (original magnification ×200).
