    Predicted to work with: Mouse
  • Immunogen

    Synthetic peptide corresponding to Nitro tyrosine (nitrated ) conjugated to Keyhole Limpet Haemocyanin (KLH).

  • Positive control
    • WB: mouse kidney lysate, mouse optic nerve, retina , spinal cord and brain lysates, rat aorta lysate(see Abreviews) IHC-P: human lung tissue (see Abreview)



Our Abpromise guarantee covers the use of ab7048 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use at an assay dependent concentration.
ICC/IF Use at an assay dependent concentration. PubMed: 22462810
ELISA Use at an assay dependent concentration.
IHC-P 1/200 - 1/400. 10% formalin fixation; 3% H2O2 to block endogenous peroxidases; Citrate buffer pH 6.0 for 1 min at 100°C as antigen retrieval treatment
IHC-Fr Use at an assay dependent concentration. Acetone fixation 10 min -20°C; block endogenous peroxidase by 0.3 % H2O2 in PBS (or methanol for intracellular staining); block with 10% NGS or 5 % BSA for 30 min.


  • Relevance
    Nitric oxide (NO) is a product of the enzymatic conversion of arginine to citrulline by nitric oxide synthase. NO reacts rapidly with superoxide to form peroxynitrite. At physiological pH and in the presence of transition metals, peroxynitrite undergoes heterolytic cleavage to form hydroxyl anion and nitronium ion, the latter of which nitrates protein tyrosine residues. Thus, the presence of nitrotyrosine on proteins can be used as a marker for peroxynitrite formation in vivo. The presence of nitrotyrosine has been detected in various inflammatory processes including atherosclerotic placques.

    • nTyr antibody


  • Immunofluorescence analysis of 22Rv1 cells (Human prostate carcinoma epithelial cell line) treated with JS-K, staining Nitro tyrosine (green) with ab7048.

    Cells were fixed with paraformaldehyde, permeabilized in 0.2% Triton X-100 and blocked with 1% BSA. Cells were incubated with primary antibody (1/25) for 30 min at 37°C. An AlexaFluor488®-conjugated anti-mouse IgG (1/100) was used as the secondary antibody.
  • ab7048 at 2 µg/ml staining Nitrotyrosine in Human liver from a severely obese patient. ab7048 was incubated for 1 hour at room temperature.
