Bioluminometric Method for Real-Time Detection of Reverse Transcriptase Activity

open access: yesBioTechniques, 1998
A simple and sensitive technique for detection of reverse transcriptase (RT) activity in real time has been developed. The technique is based on continuous detection of the inorganic pyrophosphate formed in the RT-catalyzed reaction by a luminometric ...

High-Temperature, Nonradioactive Primer Extension Assay for Determination of a Transcription-Initiation Site

open access: yesBioTechniques, 1998
We have developed a simple and safe method for the determination of a transcription-initiation site. In this method, reverse transcriptase of the avian myeloblastosis virus or rTth DNA polymerase from Thermus thermopilus was used with a fluorescein ...

Rapid detection of wheat yellow mosaic virus by reverse transcription loop-mediated isothermal amplification

open access: yesVirology Journal, 2011
For the detection of wheat yellow mosaic virus (WYMV), we established a reverse transcription loop-mediated isothermal amplification (RT-LAMP) method.

A study on the isolation of leukemia virus of AKR mouse by fluorocarbon [PDF]

open access: yes, 1962
The authors have succeeded in isolating a biologically-active leukemia virus from leukemic tissues of AKR mice with a fluorocarbon. From the chemical analysis of the biologically-active virus fraction it has been clarified that the AKR leukemia virus is ...

The GAMYB gene in rye: sequence, polymorphisms, map location, allele-specific markers, and relationship with α-amylase activity

open access: yesBMC Genomics, 2020
Background Transcription factor (TF) GAMYB, belonging to MYB family (named after the gene of the avian myeloblastosis virus) is a master gibberellin (GA)-induced regulatory protein that is crucial for development and germination of cereal grain and ...

Evidence that the RNAseH activity of the duck hepatitis B virus is unable to act on exogenous substrates

open access: yesBMC Microbiology, 2001
Background The hepadnaviral reverse transcriptase can synthesize DNA on its native RNA template within viral cores but it is usually unable to synthesize DNA employing exogenous nucleic acids as a template.

Electron microscopy of Rous sarcoma virus genome RNA and its heat-dissociated subunits [PDF]

open access: yes, 1975
Native and heat-treated RNAs from the purified Schmidt-Ruppin strain of Rous sarcoma virus (RSV) were fractionated by sucrose density gradients in the presence of ribonuclease inhibitor diethyl-pyrocarbonate and observed by electron microscopy.

Reverse Transcriptase Adds Nontemplated Nucleotides to cDNAs During 5′-RACE and Primer Extension

open access: yesBioTechniques, 2001
In determining the terminal sequences of the genomic dsRNAs of rotavirus by 5′-rapid amplification of cDNA ends (5′-RACE), it was found that most of the viral cDNAs contained extra nucleotides at their 5′ termini that had not been reported before on any ...

In vitro transformation of lymphoid cells by Abelson murine leukemia virus [PDF]

open access: yes, 1975
Cell cultures prepared from fetal murine liver were infected by Abelson murine leukemia virus. After about 2 weeks, proliferating cells of lymphoid morphology appeared in some of the cultures.

RNA Quantitative Analysis from Fixed and Paraffin-Embedded Tissues: Membrane Hybridization and Capillary Electrophoresis

open access: yesBioTechniques, 1998
Fixed and paraffin-embedded tissues from pathology department archives are available for RNA expression analysis. We describe a general method for quantitation of specific RNA sequence extracted from single 6–8-μm human histological tissue sections cut ...
