Nitrotyrosine Affinity Sorbent

Cayman Chemical Item Number 389549

The Nitrotyrosine Affinity Sorbent is designed for IP of nitrated proteins from biological samples. This is an effective way to concentrate nitrated proteins for subsequent detection by a different anti-nitrotyrosine antibody, such as Cayman’s nitrotyrosine polyclonal antibody (Catalog No. 189540), by WB analysis. Nitric oxide (NO) is a product of the enzymatic conversion of arginine to citrulline by nitric oxide synthase. NO reacts rapidly with superoxide (6.7 x 109 M−1sec−1) 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.1,2 Nitrotyrosine has been shown to be present in proteins from a variety of clinical conditions including artherosclerotic lesions of human coronary arteries, postischemic heart, and placenta during preeclampsia.3,4,5 Increased nitration of proteins in motor neurons has been identified in patients with ALS (amyotrophic lateral sclerosis) and may be due to mutations in superoxide dismutase.2,6,7,8
