# Consumable Catalog Numbers for the iSeq 100

The iSeq 100 uses two consumable components for sequencing, the flow cell and the reagent cartridge. These two components are purchased together in a single sequencing kit with different quantity packs. The catalog numbers are provided below:

* 20031371 - iSeq 100 i1 Reagent Kit v2 (300-cycle)
* 20031374 - iSeq 100 i1 Reagent Kit v2 (300-cycle), 4-pack
* 20040760 - iSeq 100 i1 Reagent Kit v2 (300-cycle), 8-pack

**Note**: Because of the improvements made in v2 iSeq 100 reagents (such reduction of no-cluster run failures and longer storage time at 2-8ยบ C), the v1 iSeq 100 reagents have been discontinued and are no longer available for sale. The iSeq 100 requires iSeq Control Software v2.0 or later to utilize the v2 reagents.

# 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/instrumentation/iseq-100/instrumentation-iseq-100-reference_material-list/000002119.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.
