Exprimental Methods

IHC
Experimental Protocol： Deparaffinization/Rehydration 1. Deparaffinize/hydrate sections: 2. Incubate sections in three washes of xylene for 5 min each. 3. Incubate sections in two washes of 100% ethanol for 10 min each. 4. Incubate sections in two washes of 95% ethanol for 10 min each. 5. Wash sections two times in dH2O for 5 min each. 6.Antigen retrieval: For Citrate: Heat slides in a microwave submersed in 1X citrate unmasking solution until boiling is initiated; continue with 10 min at a sub-boiling temperature (95°-98°C). Cool slides on bench top for 30 min. Staining 1. Wash sections in dH2O three times for 5 min each. 2. Incubate sections in 3% hydrogen peroxide for 10 min. 3. Wash sections in dH2O two times for 5 min each. 4. Wash sections in wash buffer for 5 min. 5. Block each section with 100–400 µl of blocking solution for 1 hr at room temperature. 6. Remove blocking solution and add 100–400 µl primary antibody diluent in to each section. Incubate overnight at 4°C. 7. Remove antibody solution and wash sections with wash buffer three times for 5 min each. 8. Cover section with 1–3 drops HRPas needed. Incubate in a humidified chamber for 30 min at room temperature. 9. Wash sections three times with wash buffer for 5 min each. 10. Add DAB Chromogen Concentrate to DAB Diluent and mix well before use. 11. Apply 100–400 µl DAB to each section and monitor closely. 1–10 min generally provides an acceptable staining intensity. 12. Immerse slides in dH2O. 13. If desired, counterstain sections with hematoxylin. 14. Wash sections in dH2O two times for 5 min each. 15. Dehydrate sections: Incubate sections in 95% ethanol two times for 10 sec each; Repeat in 100% ethanol, incubating sections two times for 10 sec each; Repeat in xylene, incubating sections two times for 10 sec each. 16. Mount sections with coverslips and mounting medium.

Biological Description

Specificity
8-Hydroxy-2'-deoxyguanosine Mouse mAb detects both endogenous and exogenous 8-hydroxy-2'-deoxyguanosine (8-OH-dG).

Clone
K11E8

Synonym(s)
8-OH-dG

Background
8-Hydroxy-2'-deoxyguanosine (8-OHdG) is a modified purine 2'-deoxyribonucleoside formed by the hydroxylation of the guanine base at the C8 position in DNA, typically resulting from oxidative damage caused by reactive oxygen species (ROS). Structurally, it consists of a deoxyguanosine molecule with a hydroxyl group at the 8th carbon of the guanine ring. 8-OHdG is widely recognized as a key biomarker of oxidative stress due to its high prevalence among oxidative DNA lesions. It accumulates in both nuclear and mitochondrial DNA and can be measured in various biological samples, including urine, tissues, and leukocyte DNA. Functionally, 8-OHdG serves as an indicator of endogenous DNA damage and has been extensively used to assess the risk and progression of cancer, aging, and degenerative diseases. Its presence reflects cellular exposure to oxidative agents and is instrumental in evaluating the impact of environmental and lifestyle factors on genomic stability.
