[Use of diethylenetriaminochloroplatinum in hybridization analysis of specific nucleic acid sequences].

Monofunctional platinum compound [Pt(dien)Cl] Cl and high-affinity antibodies against DNA-[Pt(dien)Cl]Cl were suggested for non-radioactive hybridisation analysis of DNA. The simple labelling procedure was based on mixing the reagents followed by the incubation for 2 h at 60 degrees C. The sensitivity and specificity of the technique were sufficient to detect 10 fg DNA in dot-hybridisation without cross-reaction with 10-fold excess of a heterologous DNA. This technique permits genome libraries screening.
