What is the significance of using HeLa cells?
HeLa cells are a standard model for studying human cell biology and are particularly useful for viral infection studies.
How is RNA isolated from infected cells?
RNA is isolated using standard extraction protocols that separate RNA from cellular components.
What is the role of reverse transcription in this protocol?
Reverse transcription converts RNA into cDNA, which is necessary for amplification and analysis.
What type of analysis is performed after RNA amplification?
Microarray analysis is performed to assess the expression levels of host and viral genes.
Can this protocol be applied to other cell types?
Yes, while this protocol uses HeLa cells, it can be adapted for other cell types as well.
