      DescriptionOxyIHC™ Oxidative Stress Detection Kit
      OverviewThe OxyIHC™ Oxidative Stress Detection Kit (S7450) contains the chemical and immunological reagents
      necessary to detect protein oxidation in various tissues from a variety of organs and animal species. The
      OxyIHC test method involves chemical derivatization of protein carbonyl groups with 2,4-
      dinitrophenylhydrazine (DNPH). This chemical reaction results in proteins being covalently coupled to DNP
      at their carbonyl sites. The DNP-derivatized proteins are then detected using an antibody that specifically
      binds to the DNP moiety. Subsequent incubation with biotin conjugated secondary antibody, streptavidin
      conjugated HRP, and development using a 3,3’ diaminobenzidine (DAB) staining allows
      immunohistochemical detection of protein oxidation.
      Background InformationReactive oxygen species (ROS) have been implicated in pathological processes including cancer,
      apoptosis, aging, neurodegenerative diseases, chronic inflammatory diseases, pulmonary diseases, and
      cardiovascular diseases (for reviews, see ref. 1-4). Living organisms are continually exposed to potentially
      harmful oxygen free radicals that are generated thru normal cellular functions as well as from environmental
      factors (1, 5-7). Yet, these reactive molecules are mitigated by the presence of antioxidants and therefore
      organisms exist with a delicate balance between oxidants and antioxidants (7-9). During times of oxidative
      stress there is an imbalance in favor of the oxidants. The end result of which is that free radicals are able to
      attack and modify sub-cellular components including nucleic acids, lipids and proteins (7, 10-12).
      Proteins are one of the major targets of reactive species. Oxidation of proteins modifies the side chains of
      methionine, histidine, and tyrosine and forms cysteine disulfide bonds (16-19). Metal catalyzed oxidation of
      proteins introduces carbonyl groups (aldehydes and ketones) at lysine, arginine, proline or threonine
      residues in a site-specific manner (16, 20-22). The oxidative modification of proteins can modulate
      biochemical characteristics of proteins such as enzymatic activity (21-23), DNA binding activities of
      transcription factors (24-26), and the susceptibility to proteolytic degradation (12, 25-28). While a
      relationship between protein oxidation and aging has been suggested (29-31), little is known about the
      importance of oxidative modification of individual proteins in the pathophysiology of free radical mediated
      processes. Not surprisingly, carbonyl modification of proteins has become a key biomarker for the
      identification of oxidative stress.
