A fluorescence in situ hybridization (FISH) method was developed to visually detect viral genomic RNA using fluorescence microscopy. A probe is made with specificity to the viral RNA that can then be identified using a combination of hybridization and immunofluorescence techniques. This technique offers the advantage of identifying the localization of the viral RNA or DNA at steady-state, providing information on the control of intracellular virus trafficking events.

This method describes the use of click chemistry to measure changes in host cell transcription after infection with the Rift Valley fever virus (RVFV) strain MP-12. Results can be visualized qualitatively via fluorescence microscopy or obtained quantitatively through flow cytometry. This method is adaptable for use with other viruses.
FAQs
Chemical lysis disrupts viral particles, while RNase inactivation protects RNA from enzymatic degradation. This combination matters because viral RNA must remain intact after release from the particle. If degradation occurs, the recovered material may be less suitable for reverse transcription, quantitative PCR, sequencing, or other molecular assays. These early steps therefore influence downstream detectability and analysis.
Silica-membrane columns and magnetic beads provide two purification formats for recovering viral RNA after lysis. In either approach, the nucleic acid is separated from disrupted sample material, washed to support purification, and then eluted for analysis. The formats differ in how the purification material is handled, but both can produce RNA for downstream molecular assays.
The intended assay determines how the recovered RNA will be used and interpreted. Reverse transcription and quantitative PCR can support detection or viral-load measurement, whereas sequencing can contribute to viral characterization. Because extraction precedes these analyses, obtaining usable RNA connects the original virus-containing sample to molecular results about presence, quantity, or sequence-related features.
A typical workflow begins by chemically lysing the virus-containing sample and limiting RNase-mediated degradation. The released nucleic acid then passes through a silica-membrane column or is captured with magnetic beads. Washing removes remaining sample-associated material, and elution recovers the purified RNA. That eluate can proceed to reverse transcription, quantitative PCR, sequencing, or another molecular assay.
Researchers use the resulting RNA for pathogen identification, viral-load measurement, outbreak surveillance, and characterization of viral material. These applications connect extraction with both clinical diagnostics and infectious-disease research. Comparing molecular results across virus-containing samples can help support surveillance activities and investigations of infection, provided the recovered RNA is suitable for the selected downstream assay.
In immunology and infection research, extracted RNA provides molecular material for examining viruses and their interactions with hosts. Reverse transcription and quantitative PCR can support detection or measurement, while sequencing can aid characterization. These outputs help investigators study infection-related processes alongside broader questions about host–virus interactions, making extraction an enabling step rather than the final analysis.
