Abstract
Mouse monoclonal antibody was elicited with 4-nitroquinoline 1-oxide (4NQO) modified poly(dG-dC).poly(dG-dC) and was characterized using enzyme-linked immunosorbent assay and radioimmunoassay. The antibody reacted specifically for 4NQO-poly(dG-dC).poly(dG-dC) but not for 4NQO modified DNA and synthetic polynucleotides such as poly(dG).poly(dC). The antibody crossreacted slightly with brominated or N-acetoxy-2-acetylaminofluorene modified poly(dG-dC).poly(dG-dC) known to adopt Z-conformation. The antibody may recognize unique conformational change in poly(dG-dC).poly(dG-dC) modified by 4NQO. The antibody should be useful for the detection of conformational change in DNA induced by chemical carcinogens.
