    A validated, affinity purified mouse monoclonal antibody clone 6B2 to nitrotyrosine

    A large number of physiological and pathological events lead to so called stress conditions to which the organism can adapt within certain limits by regulating the activity of a series of enzymatic cascades. Most stress responses are characterized by an increased generation of “free radicals” which encompass both reactive oxygen (ROS) and nitrogen species (RNS). Most of these species react with macromolecules of the organism, i.e. amino acids, proteins, lipids and DNA, leading to functional alterations which can either participate to adaptation or lead to cell death.

    Oxidative stress however, has different functional consequences depending not only upon its intensity and duration, but also upon the nature of the free radicals, ROS or RNS, generated. Interestingly, the nature of these reactive species depends on the ratio between the initially produced ROS, superoxide anion (O2.-), and nitric oxide (NO). Indeed, O2.- very rapidly reacts with NO and therefore, as long as the NO/ O2.- ratio is = 1, O2.- will therefore preferentially react with NO rather than with macromolecules, thus generating reactive nitrogen species (RNS): nitrosonium (NO+), N2O3 and peroxinitrite (ONOO-). These RNS induce posttranslational modifications: for NO+ and N2O3, S-nitrosation (Cys-SNO) and for ONOO- tyrosine nitration (Tyr-NO2), methionine sulfoxidation (Met-SOH) and thiol oxidation (RS-S-R). When the O2./ NO ratio becomes > 1, the O2.- and NO.2 ions and thereafter the OH. radicals cause irreversible oxidations and peroxidations of macromolecules which generally lead to cell death(1-4). The monoclonal antibodies have been selected for their high affinity and specificity towards Tyr-NO2 residues. They do not cross-react with Tyr or Tyr derivatives such as aminotyrosine, chlorotyrosine or phosphotyrosine, neither with nitroTrp which can also be generated in response to peroxynitrite. They also recognize Tyr-NO2 residues in various sequences as shown by their ability to recognize nitrated proteins including albumin, ovalbumin, insulin, hemoglobin, KLH and various cytoplasmic and mitochondrial proteins.
