New 8-OHdG Check ELISA
Suitable for assessment of oxidative stress using urine samples. For research use only.
About 8-hydroxy-2'-deoxyguanosine (8-OHdG):
8-hydroxy-2'-deoxyguanosine (8-OHdG) is a product of oxidatively damaged DNA formed by hydroxy radical, singlet oxygen and direct photodynamic action. 8-OHdG can be detected in tissue, serum, urine and other biomaterials. New 8-OHdG Check is a competitive enzyme-linked immunosorbent assay (ELISA) utilising monoclonal antibody (clone N45.1) which is highly specific for DNA damage, not cross react with RNA oxidation products such as 8-hydroxy-guanine and 8-hydroxy-guanosine. This product is suitable for detection of 8-OHdG in urine and other biomaterials from human and animals.
This product is a 8-OHdG ELISA kit utilizing anti 8-OHdG monoclonal antibody (clone N45.1) which is highly specific for 8-OHdG. We provide two types of 8-OHdG ELISA kits with different assay range. New 8-OHdG Check ELISA is suitable for urine and serum sample from animal and human. If you are planning to measure 8-OHdG in human serum,tissue, cultured cells, we recommend to use 'Highly Sensitive 8-OHdG Check ELISA'.
Assay principle: Competitive ELISA (detection: 450 nm)

Measuring range: 0.5 to 200 ng/mL
Format: 96 wells (18 samples in triple assays)
Applications: Urine from human and animals.
For serum and tissue samples, Highly Sensitive 8-OHdG Check (code #KOG-HS10E) is recommended.
Storage: Store at 4 - 10°C (don't freeze).
Expiry: 12 months after the day of manufacturing.
Required but not provided: Micropipet and chip (100 micro L, 1000 micro L).
Measuring pipet (10 mL, 20 mL)/ measuring cylinders.
8 or 12-syncronous multichannel pipet and reagent tray for multichannel pipet.
Microplate reader (filter; 450 nm).
