Reagent Kits
NextSeq 500/550 v2 kits have been discontinued. In addition, NextSeq TG reagents v1, v1.2, and v2 were discontinued on October 31, 2019, and the NextSeq TG v2.1 reagents were discontinued on July 31, 2019. With increased stability, the NextSeq 500/550 v2.5 Kits are the recommended replacement.
Catalog IDs: FC-420-1001, FC-420-1002, FC-420-1003, FC-420-1004
Kit Requirements
Performing a sequencing run requires a single-use NextSeq 500/550 Kit. Each kit contains a flow cell and reagent cartridge prefilled with reagents used for clustering the flow cell and performing the run.
The NextSeq 500/550 Kit (v1) requires manually adding sodium hypochlorite (NaOCl) and BP13 to the reagent cartridge before the run. For instructions, see Additional Setup Step for NextSeq 500 Kit v1. All other kits include dual-index sequencing primers and NaOCl in the prefilled cartridge. No additional steps are required.
For other system requirements and product compatibility, see Compatible Products.
Flow Cell Types
Each reagent cartridge and flow cell is marked High or Mid for easy identification. Use the appropriate reagent cartridge for a given flow cell type. The buffer cartridge is universal.
