Circulating free nitrotyrosine in obstructive sleep apnea

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2004
Obstructive sleep apnea (OSA) has been increasingly linked to cardiovascular disease, endothelial dysfunction, and oxidative stress, generated by repetitive nocturnal hypoxemia and reperfusion. Circulating free nitrotyrosine has been reported as a novel biomarker of nitric oxide (NO)-induced oxidative/nitrosative stress.

Choice of different dyes to label tyrosine and nitrotyrosine

Journal of Chromatography A, 2002
In this work, we will present some attempts to analyze tyrosine and nitrotyrosine using capillary electrophoresis and either UV-Visible detection or laser-induced fluorescence (LIF) detection. An argon ion (488 nm) laser is used for fluorescein isothiocyanate (FITC) and 7-fluoro-4-nitro-2,1,3-benzoxadiazole (NBD-F).

Plasma nitrotyrosine levels, antioxidant vitamins and hyperglycaemia

Diabetic Medicine, 2005
AbstractAims  Studies on plasma nitrotyrosine (NT) levels, a measure of oxidative injury, in diabetes are limited and discordant; the amount of antioxidants might represent a possible explanation for the discordant results. The aim of this paper is to evaluate the association between plasma NT levels and glucose tolerance status, according to ...

Nitrotyrosine internal standard for amino acid analysis

Analytical Biochemistry, 1975
Abstract 3-Nitrotyrosine is shown to be suitable as an internal standard for amino acid analysis. It is stable to acid hydrolysis, gives a color yield of 1.01 with ninhydrin which obeys Beer's Law, elutes in a position which is resolved from other amino acids on both Spinco and Durrum amino acid analyzers, and is commercially available.

Immunohistochemical methods to detect nitrotyrosine.

Methods in enzymology, 1999
The immunohistochemical detection of nitrotyrosine is a robust method for detecting peroxynitrite and other reactive nitrogen species. Success depends on optimizing conditions for the particular tissue and experimental design under investigation and the use of positive and negative controls to verify specificity.
