The avidin/biotin system was introduced into the standard enzyme-linked immunosorbent assay (ELISA) to increase its sensitivity for detecting UV lesions in human DNA. Goat anti-rabbit IgG-peroxidase used in the standard ELISA as second antibody was replaced by biotinylated goat anti-rabbit IgG plus the avidin-biotin-peroxidase complex (ABC) reagent. Sensitivity of detection of plate-fixed UV-DNA-antibody complexes was increased about 8-fold and photolesions in human DNA samples irradiated with as low a dose as 1 J/m2 UVC or a suberythemal dose of UVB light could be detected.
