Description
• Measure CPD structures of DNA lesions induced by UV light
• Detect structures in isolated DNA using standard ELISA plate format
Our OxiSelect UV-Induced DNA Damage ELISA Kit measures the formation of cyclobutane pyrimidine dimers (CPD) in DNA isolated from cells or tissues. Standards or unknown DNA samples are first heat denatured before adsorbed onto a 96-well DNA binding plate. The sample or standard are then probed with an anti-CPD antibody, followed by an HRP conjugated secondary antibody.
Introduction: Absorption of ultraviolet (UV) light produces two predominant types of DNA damage, cyclobutane pyrimidine dimers (CPD) and pyrimidine (6-4) pyrimidone photoproducts (6-4PP) (Figure 1). The result is a transition of C to T and CC to TT, which are the most frequent mutations of p53 in both human and mouse skin cancers. UV damaged DNA is usually repaired by nucleotide excision repair (NER) or base excision repair (BER). After UV exposure, cells activate p53 and stall the cell cycle for repair. If the damage is too severe, the cell will trigger apoptosis to get rid of DNA damaged, potentially mutant cells.
MyBioSource's OxiSelect Oxidative UV-induced DNA Damage ELISA Kit (CPD Quantitation) is an enzyme immunoassay developed for rapid detection and quantitation of CPD in any DNA samples. The quantity of CPD in unknown sample is determined by comparing its absorbance with that of a known CPD-DNA standard curve. Each kit provides sufficient reagents to perform up to 96 assays, including standard curve and unknown samples
