This Nitrotyrosine BSA can be used as a positive control for immunoblotting experiments using Nitrotyrosine Polyclonal Antibody and Nitrotyrosine Monoclonal Antibody.
- Storage buffer: 500 μl PBS at pH 7,2
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.
Nitrotyrosine has been shown to be present in proteins from a variety of clinical conditions including atherosclerotic lesions of human coronary arteries, postischemic heart, and placenta during preeclampsia. Increased nitration of proteins in motor neurons has been identified in patients with amyotrophic lateral sclerosis and may be due to mutations in superoxide dismutase.
Pozor: This product is not for human or veterinary use. Recommended concentration for use as positive control is 50 to 100 ng.
