Reactivity of the Co(III) complex of cyclen (CoCyc) in the hydrolytic cleav
age of supercoiled pUC18 DNA leading to the formation of the corresponding
open circular form was enhanced by > 200 times upon attachment of CoCyc to
cross-linked polystyrenes. Thus, half-lives as short as 40 min were achieve
d by the resin-based CoCyc in cleavage of the supercoiled DNA Lit 4 degrees
