Antibodies against DNA Damage

Anti Cyclobutane Pyrimidine Dimers (CPDs) [Clone : TDM-2]
Anti (6-4) photoproducts (6-4 PPs) [Clone : 64M-2]
Anti Dewar photoproducts (Dewar PPs) [Clone : DEM-1]


Prolonged exposure to solar UV radiation may result in acute and chronic health effects on the skin, eye, and immune system, including skin cancers. These harmful effects are suggested to deeply relate to DNA damage. The major types of DNA damage induced by solar UV radiation are cyclobutane pyrimidine dimers (CPDs), (6–4) photoproducts (6-4PPs), and Dewar photoproducts (DewarPPs), which are formed between adjacent pyrimidine nucleotides on the same strand of DNA. These helix-distorting DNA lesions are repaired exclusively by nucleotide excision repair system in humans. Mori et al. have developed and characterized monoclonal antibodies specific for CPDs or 6-4PPs (1). Matsunaga et al. have established and characterized monoclonal antibodies against DewarPPs (2). These antibodies enable one to quantitate photoproducts in DNA purified from cultured cells or from the skin epidermis using an enzyme-linked immunosorbent assay (ELISA) and to visualize and measure photoproducts in DNA in cultured cells or the skin using indirect immunofluorescence. Thus, this technology would contribute to understanding of molecular mechanisms of cellular responses to UV and DNA damage in many research fields including cancer research, photobiology, dermatology, ophthalmology, immunology, and cosmetology.

The technique of micropore UV irradiation combined with fluorescent antibody labeling is very powerful for examining whether a protein of interest is recruited to the sites of UV-induced DNA damage. Micropore UV irradiation induces UV-damage at localized areas of nuclei using a polycarbonate isopore membrane filter. The polycarbonate blocks UV radiation, and cells are exposed only through the 5 µm pores of the filter. 0.5 h after micropore UV irradiation, cells were fixed and Immunofluorescent double staining for DNA damage and repair protein were performed.

Cells were doubly stained for XPB and for CPD 0.5 h after local UV irradiation. In normal MSU-1 cells, XPB foci overlapped with the corresponding CPD foci, indicating that XPB is quickly recruited to the sites of DNA damage for repair. In contrast, no or less bright XPB foci at the DNA damage sites were observed in repair deficient TTD cell lines.


Genomic DNA is purified from UV-damaged cells and denatured DNA is coated on wells of 96-well plate. The binding of TDM-2 or 64M-2 to DNA damage is detected by sequential treatment with biotinylated 2nd antibody and streptavidin-peroxidase. Then, the absorbance of colored products derived from OPD is measured at 492 nm.

Normal human cells repair 90% of the initial 6-4PP within 3 h after UV irradiation, while they remove 50% of the initial CPD within 24 h. Both damage are repaired by the same nucleotide excision repair (NER) pathway, but 6-4PP forms bigger distortion in DNA than CPD does, resulting in much more efficient repair. In contrast, repair deficient XP-C cells can not repair both damage at all.

Feature and Advantages:

  • Very specific for the particular UV-induced DNA lesion

  • Research applications include ELISA, IF, and IHC

  • Useful for research in DNA damage and repair

  • Visualizes the DNA damage repair process

  • Applicable to a broad range of research fields including cancer research, photobiology, dermatology, ophthalmology, immunology, and cosmetology
