The activity of NADPH-diaphorase (NADPH-d), a marker for nitric oxide synthase (NOS), was examined histochemically in the rat and mice retina. Mice in which the neuronal NOS gene has been disrupted (nNOS- mice) were used for specificity controls. Light microscopically

We investigated the subcellular localization of nicotinamide adenine dinucleotide phosphate diaphorase (NADPH-d) activity, a histo- and cyto-chemical marker of nitric oxide synthase, in human placental trophoblast obtained from women with normal term pregnancies. Tetrazolium salt BSPT was used as the
L Villani et al.
Brain research, 743(1-2), 353-356 (1996-12-16)
The localization of nitric oxide synthase and NADPH-diaphorase was studied in the goldfish retina by means of immunohistochemistry or tetrazolium salt technique. Nitric oxide synthase was found in some small neurons of the inner nuclear layer and in large neurons
S Barbey et al.
Pathology, research and practice, 182(6), 805-809 (1987-12-01)
The ultrastructural and histochemical exploration of histiocytes X done by the means of Concanavalin A (Con A), peanut agglutinin (PNA) and BSPT demonstrate that the plasma membrane of histiocytes X shared some properties with all the other cells and is
G Wolf et al.

The 2-(2'-benzothiazolyl)-5-styryl-3-(4'-phthalhydrazidyl) tetrazolium chloride (BSPT)-tetrazolium salt technique for the electron microscopic demonstration of reduced nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) was used to localize nitric oxide synthase in the normal and excitotoxically lesioned rat hippocampus. The reaction product BSPT-formazan was shown
