Two modified polynucleotides having the Z-DNA conformation (poly [dG-dC] dien Pt and poly [dG-br5dC] . poly [dG-br5dC]) have been used for determination of antibodies to Z-DNA. Such antibodies were found in sera of patients with systemic lupus erythematosus and with Crohn's disease. They were scarcely observed in polyradiculoneuritis and in amyotrophic lateral sclerosis. In Crohn's disease sera, no antibodies to B-DNA were ever found but presence of two different families of antibodies to Z-DNA was demonstrated.
