3-nitrotyrosine

3-Nitrotyrosine is a post-translational modification of the amino acid tyrosine, where a nitro group (-NO2) is added to the 3-position of the aromatic ring.
This modification can occur due to nitrosative stress and is a marker of oxidative damage. 3-Nitrotyrosine has been linked to a variety of pathological conditions, including neurodegenerative disorders, cardiovascular disease, and cancer.
Accurate and reproducible detection and quantification of 3-nitrotyrosine levels is crucial for understanding its role in disease processes and developing targeted therapies.
PubCompare.ai's AI-driven protocol comparison tool can help researchers quickly identify the most reliable methods from the literature, preprints, and patents to power thier 3-nitrotyrosine studies with confidence and maximiize the impact of their research.

Carotid plaques were removed by standard surgical techniques and minimal manipulation to the specimens. Immediately after the surgery, plaques were stored in phosphate buffered saline (PBS) at 4°C. The specimens were embedded into an optimum cutting temperature (OCT) compound (LEICA, 020108926) and stored at -80°C for further analysis. Samples were analyzed by immunohistology, immunohistochemistry, and immunofluorescence using confocal microscopy. For immunohistochemistry plaque samples were analyzed for various CD cellular markers including CD66b, CD163, CD68, and lipids. Additional cellular markers were used for confocal microscopy. Quantitative analyses of the expression of various markers were performed as previously described (2 (link), 15 (link)) and as specified below. Mouse monoclonal primary antibodies were used to identify neutrophils (anti-CD66b), macrophages-foam cells (anti-CD163) and anti-3-nitrotyrosine for oxidative-nitrosative stress. Rabbit primary polyclonal antibodies were used for double-labeling the cells with additional markers including scavenger receptors anti-CD68 and anti-CD36, anti-NE, anti-MPO, anti-Vascular Endothelial Growth Factor (VEGF), anti- CD31, and anti- smooth muscle actin (SMC-actin). Polyclonal anti-CD163 was used for double-labeling with anti-CD66b. Intra/extra cellular lipids and lipid crystals were determined by immunohistochemistry with Oil Red O staining (15 (link)).

The optical fractionator method of stereology of the stereo-investigator software
(MBF Biosciences) was used to quantify nitrotyrosine, cleaved caspase 3, and
NeuN immuno-reactive cells in the hippocampal dentate gyrus region. For all
measurements, six sections were obtained to cover the entire impact region,
−1.60 mm to −6.3 mm from Bregma, corresponding to every 12 serial sections for
each brain. For the stereological quantitation, we used a grid spacing of 75  μm
× 75 μm in the x and y-axis and guard zones of 2 μm at the top and bottom of
each section where immuno-positive cell bodies were counted. The total number of
nitrotyrosine, cleaved caspase 3, and NeuN-positive cells in the volume of
interest were automatically determined and expressed as
cells/mm3.
Image J software (NIH) was used to measure immunoblot protein band signal
intensity, the internal length, and the central width of each endothelial
nucleus.
