title: Asymmetric cooperativity in tandem hybridization of enantiomeric metal complex-tethered short fluorescent DNA probes.
abstract: The complex [Ru(phen)(2)(dppz)](2+)(phen = 1,10-phenanthroline, dppz = dipyrido[3,2-aratio2',3'-c]phenazine) was attached to the 5' end of a short oligonucleotide to form conjugates, the Delta-isomer of which showed a high cooperativity during the recognition of the repetitive sequence, while the Lambda-isomer did not.
