# 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," the catalog numbers for which 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 (reduction of no-cluster run failures, longer storage time at 2-8° 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.
