Figure 4. PLA2R Immunohistochemistry. A. Control: negative PLA2R. No granular immunostaining at the capillary walls; there is normal scattered PLA2R immunostaining in podocytes. B: positive granular global PLA2R immunostaining at the basement membrane of the glomerular capillary walls; C: Positive IgG4. Granular immunostaining at the basement membrane of the capillary walls (40×). Primary antibodies: anti-PLA2R (1:2500, Sigma) and IgG4 (1:3000, Gene Tex).
