Cerium(IV)/Lanthanide(III)/Dextran Ternary Solutions for Efficient and Homogeneous DNA Hydrolysis

Homogeneous and neutral solutions are prepared by mixing Ce(NH4)2(NO3)6 and dextrans at pH 7. These homogeneous solutions are active for DNA hydrolysis. Still more importantly, the activities of the binary solutions are greatly promoted by the addition of various lanthanide(III) ions.
