Elimination of residual RNase activity from purified preparations of RNA-directed DNA polymerase

Biochemical and Biophysical Research Communications, 1975
Abstract Preparations of RNA-directed DNA polymerase purified from RNA tumor viruses by standard methods generally contain trace amounts of single-stranded RNA endonucleolytic activity detectable only by relatively sensitive methods. This contaminating RNase activity has been found to be completely inhibited when RNA-directed DNA polymerase reactions

RNA-directed DNA polymerase activity of reticuloendotheliosis virus: characterization of the endogenous and exogenous reactions

Journal of Virology, 1975
Reticuloendotheliosis virus (REV) contains an endogenously instructed, RNA-directed DNA polymerase activity. Both the endogenous and exogenous DNA polymerase activities exhibited up to 10-fold greater activity at the optimum concentration of manganous ion (0.025 mM for exogenous; 0.25 mM for endogenous) than at any concentration of magnesium ion ...

RNA-Directed DNA Polymerase Activity in Human Breast Cancer Biopsy Specimens

Oncology, 2009
The expression of a mouse mammary tumor virus is inducible by hormones, and the virus contains a hormone-responsive element. Viral particles and RNA-directed DNA Polymerase (RDDP, EC 2.7.7.7; reverse transcriptase) are both detectable in human breast tumors but the frequency and significance of these findings are unknown. Breast tumor biopsy specimens (

Ionophorous polymers. Interaction with polynucleotides and effects on RNA-directed DNA polymerase activity.

Biochimica et biophysica acta, 1976
Poly(vinylbenzo-18-crown-6), a water-soluble polymer endowed with ion-binding crown moieties as pendent groups, forms insoluble complexes with polyadenylate in the presence of K+; the corresponding monomeric benzo-18-crown-6, does not form a precipitate under the same conditions.
