  • RelevanceIn intact animals, lesions (adducts) excised from DNA are transported from the cell through the circulation and excreted in urine. In bacteria, DNA adducts are excreted directly into the medium. In either case, the adducts can be assayed as a measure of oxidative damage to DNA. In particular, Oxo-8-dG (8-Oxo-7,8-dihydro-2'-deoxyguanosine) serves as an excellent marker for DNA damage produced by oxidants because it represents one of the major products generated by a wide array of treatments associated with oxidant damage such as that produced by irradiation and various carcinogens and because it is implicated in spontaneous transversion mutagenesis. Oxo-8-Gua (8-oxo-7,8-dihydroguanine) is one of the most common DNA lesions resulting from reactive oxygen species and can result in a mismatched pairing with adenine resulting in G to T and C to A substitutions in the genome. In humans, it is primarily repaired by DNA glycosylase OGG1. It can be caused by ionizing radiation, in connection with oxidative metabolism. Oxo-8-G (8-oxo-7,8-dihydroguanosine) is classified as an oxidized ribonucleotide, and is primarily used in studies of oxidative RNA damage and associated RNA repair and RNA turnover mechanisms within the cell. In the cell, Oxo-8-G RNA lesions are formed by reaction with reactive oxygen species (ROS) generated either via normal oxidative metabolic processes, UV ionizing radiation, or exposure to oxidative agents. Oxidative RNA damage can lead to defects in protein synthesis, for example, decreased rates of protein synthesis and production of aggregated or truncated peptides, with important implications in aging and neurodegenerative disorders and artherosclerosis.

  • Immunohistochemical analysis of PFA-fixed paraffin-embedded rat femural tissue, labelling with ab62623 at a dilution of 1/50 incubated for 13 hours at 4°C in 1% BSA in TBS. Heat mediated antigen retrival was performed via Tris-EDTA pH 9.0. Blocking was via ab93695 ABC kit incubated at 1% for 20 minutes at room temperature. A sexondary was not used, but ab93695 detection kit was used for signal amplification.

  • ab62623 staining in rat liver tissue section by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue underwent formaldehyde fixation before enzymatic antigen retrieval with Proteinase K solution and then blocking for 20 minutes at 37°C was performed. The primary antibody was diluted 1/4000 and incubated with sample for 2 hours at 37°C. A Biotin conjugated rabbit polyclonal to mouse IgG was used as secondary antibody at 1/200 dilution.
