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