DNA damage can take many forms including oxidative damage, hydrolytic damage (loss of bases) and strand breaks. Continuous DNA damage has been implicated in age-related development of a variety of cancers including colon, breast and prostate.

In this article we discuss various assay kits to help measure DNA damage in a quick and reliable way. Read on for further details.





8-hydroxydeoxyguanosine (8-OHdG) is a popular and ubiquitous marker of oxidative stress.

Our OxiSelect™ Oxidative DNA Damage ELISA Kit provides a powerful, well-published method for rapid, sensitive quantitation of 8-OHdG in DNA samples.

UV Induced DNA Damage Assays

Absorption of ultraviolet (UV) light produces two predominant types of DNA damage: cyclobutatne pyrimidine dimers (CPD) and pyrimidine (6-4) pyrimidone photoproducts (6-4PP).

Our OxiSelect™ Oxidative UV-Induced DNA Damage Assay Kits provide rapid detection and quantitaiton of CPD or 6-4PP. Kits are available in ELISA format for isolated DNA or intact cells, and also in a cellular staining format.

OxiSelect™ Comet Assays

The comet assay is a well-published method for measuring cellular DNA damage.

Our OxiSelect™ Comet Assays provide a fast, convenient way to measure DNA damage on a macro level, regardless of the source or nature of the damage.
