# Respiratory Virus Enrichment Kit sequencing recommendations and public data resources

**What is the recommended read length?**\
A 2x75 bp read length is recommended when sequencing Respiratory Virus Enrichment Kit (RVEK) libraries, prepared with the Respiratory Virus Oligos Panel v2 (RVOP v2). This shorter read length takes into account the potentially shorter average size of libraries created with samples of variable quality.

**What is the recommended read depth?**\
1 million reads per sample are recommended as a starting point, labs can adjust based on data needs.

**Are there public datasets available?**\
Yes, the following public datasets are available in BaseSpace Sequence Hub.\

Please note that this kit was previously named the Respiratory Virus Oligo Panel v2 kit, and has been renamed to the Respiratory Virus Enrichment Kit, which still uses the Respiratory Virus Oligo Panel v2 for enrichment.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://knowledge.illumina.com/library-preparation/general/library-preparation-general-reference_material-list/000003426.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
