title: Antibodies raised against guanosine bind to double-stranded DNA.
abstract: Antibodies elicited against guanosine have been reported to bind to single-stranded DNA. Using an avidin-biotin microELISA, we report that these antibodies also bind to double-stranded DNA. The binding is specific and is completely inhibited by the homologous hapten. The cross-reactivity of double-stranded DNA binding antibodies to single-stranded DNA is low. The antibodies are shown to bind to the topoisomers of plasmid DNA as assessed by a gel retardation assay.
