3-Nitrotyrosine immunohistochemistry was performed on paraffin section of three cases of normal renal parenchyma.
−=no staining; ±=heterogeneous positive staining; +=homogeneous positive staining.
NOS1 staining pattern already fully described in normal kidney in a previous paper (Jarry et al, 2003).
