Immunohistochemical staining of formalin fixed paraffin embedded liver sections of A a non-infected mouse and B a Toxoplasma (T.) gondii infected mouse using rat anti-iNOS (cat. no. HS-484 017; 1 : 1000, DAB). Nuclei have been visualized by haematoxylin staining (blue).​

Immunohistochemical staining of formalin fixed paraffin embedded A Cloudman S91 syngeneic tumor and B KP1 syngeneic tumor with rat anti-iNOS (cat. no. HS-484 017; 1 : 200, DAB). Nuclei have been visualized by haematoxylin staining (blue).​

Immunohistochemical staining of formalin fixed paraffin embedded in vitro differentiated mouse macrophages with rat anti-iNOS (cat.  no. HS-484 017, 1 : 5000; DAB). High iNOS expression is detected in macrophages differentiated in presence of interferon-γ (IFNγ) and lipopolysaccharide (LPS). Unstimulated macrophages or macrophages differentiated in presence of IL-4 are negative. Nuclei have been visualized by haematoxylin staining (blue).

Immunohistochemical staining of formalin fixed paraffin embedded spleen (A, B) or lung (C, D) sections of a non-infected mouse (A, C) or a Toxoplasma (T.) gondii infected mouse (B, D) using rat anti-iNOS (cat. no. HS-484 017; 1 : 1000, DAB). Nuclei have been visualized by haematoxylin staining (blue).
