Indian Journal of Medical Research. 1990 Jun; 92(): 158-62http://imsear.searo.who.int/handle/123456789/21380A high degree of specificity of circulating anti-DNA antibody for double stranded DNA in the sera of SLE patients was found, as compared to single stranded polymer. The antibody recognized brominated DNA, a polymer that appears to attain Z-conformation as indicated on the basis of UV absorption characteristics. The existence in native DNA of regions undergoing B----Z transition has been detected.engAntibody SpecificityAutoantibodies --bloodDNA --immunologyHumansLupus Erythematosus, Systemic --immunologyNucleic Acid ConformationJournal Article
