The interaction of [Ru(NH3)5Cl]2+ and [Ru(NH3)6]3+ ions with DNA.

Abstract

The interaction of [Ru(NH3)5Cl]2+ and [Ru(NH3)6]3+ complex ions with calf thymus DNA has been studied at various r values (r = [Mn+]/[DNA-P]). Electronic spectra of metal-DNA solutions have been recorded and compared to the spectra of metal, as well as of DNA, solutions. Melting curves have been taken for the determination of DNA melting temperature (Tm) in… (More)
