The increasing importance of nitric oxide synthase has been underscored by the elucidation
of its role in a growing number of normal and pathophysiological processes. Therefore …

Nitrite and nitrate determinations in biological fluids are increasingly being used as markers
of nitric oxide production. We have modified a nitrate reductase and Griess reaction method …

Plasma nitrite and nitrate determinations are increasingly being used in clinical chemistry as
markers for the activity of nitric oxide synthase and the production of nitric oxide radicals …

Quantification of nitric oxide in vivo is difficult because of its short half-life. Instead the
oxidised products, nitrite and nitrate, are commonly used as indices of nitric oxide …

Measurements of nitrite and nitrate are used in biomedical research to estimate the
endogenous formation of nitric oxide (an important biomolecule). These anions are also …

Nitric oxide (NO) is an important intra-and intercellular mediator. Although NO can be
measured using many different chemical methods, the compound is challenging for a …

Before the discovery of nitric oxide synthases in biological systems, measurements of nitrite
and nitrate were primarily the tasks of chemists concerned with accumulation of oxides of …

Objective: To review the assays available for measurement of nitrite and nitrate ions in body
fluids and their clinical applications. Design and Methods: Literature searches were done of …

Numerous methods are available for measurement of nitrate (NO− 3). However, these
assays can either be time consuming or require specialized equipment (eg, nitrate …

The nitric oxide radical (NO) plays an important role as a physiological messenger [1]. NO is
formed from l-arginine [2] by NO synthase (NOS; EC 1.14. 13.39), which exists in several …
