Influenza A virus encoding secreted Gaussia luciferase as useful tool to analyze viral replication and its inhibition by antiviral compounds and cellular proteins. [PDF]

PLoS ONE, 2014
Reporter genes inserted into viral genomes enable the easy and rapid quantification of virus replication, which is instrumental to efficient in vitro screening of antiviral compounds or in vivo analysis of viral spread and pathogenesis.

Applicability of Different Methods for Quantifying Virucidal Efficacy Using MENNO Florades and Tomato Brown Rugose Fruit Virus as an Example

Plants, 2023
After entry of a quarantine/regulated pathogen, infected plants shall be destroyed, and the cultivated area (e.g., greenhouse) shall be disinfected. Therefore, the selection of an effective disinfectant plays an important role.

Quantifying Lipid Contents in Enveloped Virus Particles with Plasmonic Nanoparticles [PDF]

, 2014
Phosphatidylserine (PS) and monosialotetrahexosylganglioside (GM1) are examples of two host-derived lipids in the membrane of enveloped virus particles that are known to contribute to virus attachment, uptake, and ultimately dissemination. A quantitative

Quantification of Influenza Virus Messenger RNAs

Journal of General Virology, 1980
The amounts of specific influenza virus cRNAs present on polyribosomes of cells treated with cycloheximide at various times after infection were measured by quantitative hybridization with 125I-labelled virus RNA segments. All species of cRNA were found associated with polyribosomes at every time point analysed.
