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 (

[15b] The preparation of RNA-directed DNA polymerase from ovaries of Xenopus laevis

1974
Publisher Summary This chapter describes the preparation of RNA-Directed DNA polymerase from ovaries of Xenopus laevi . Young oocytes of Xenopus laevis synthesize DNA that corresponds to a selected portion of the chromosome—the genes coding for ribosomal RNA.
