Inhibition of DNA restriction enzyme digestion by anthracyclines [PDF]

open access: possibleLa Ricerca in Clinica e in Laboratorio, 1988
The inhibition of restriction enzyme digestion of lambda phage DNA by anthracyclines (i.e., adriamycin, daunomycin, epirubicin, idarubicin and esorubicin) commonly used in the treatment of human leukemia and cancer has been studied in vitro. The anthracyclines used inhibit DNA digestion by SmaI, AvaII, HaeIII, HhaI and HpaII, which cut DNA at guanine ...

DNA Restriction Enzyme from E. coli [PDF]

open access: possibleNature, 1968

Restriction enzyme analysis of the Plasmid ColIb DNA

Molecular and General Genetics MGG, 1979
Plasmid ColIb (61.5 Mdal) was digested with restriction enzymes EcoRI and HindIII. The DNA digestion products were separated by electrophoresis on 1.2% agarose gels. There were identified 22 fragments of ColIb DNA generated by the endonuclease EcoRI and 21 fragments produced by HindIII. Molecular weights of the fragments were estimated.

Restriction enzyme cleavage of ultraviolet-damaged DNA

Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, 1982
SV40 and pBR322 DNAs damaged by ultraviolet light were cleaved abnormally by several restriction enzymes because of damage to pyrimidines in the recognition sequences. The use of a tandemly duplicated plasmid provided a particularly sensitive target molecule for detecting pyrimidine dimers and other possible photoproducts.
