Chapter 3 Sequencing in HiSeq v4 Mode
Sequencing in HiSeq v4 Mode
Introduction
To perform a sequencing run in HiSeq v4 mode on the HiSeq 2000, prepare all reagents and then follow the
software prompts to set up the run. Run setup steps include entering run parameters, loading and priming
reagents, loading the flow cell, and performing a fluidics check.
Visit the HiSeq 2000 specifications page on the Illumina website for information about run duration and other
performance specifications.
Staggering Runs
You can start a new run on either flow cell A or flow cell B when a run on the adjacent flow cell is in progress.
For more information, see
Stagger Runs on Flow Cell A and Flow Cell B
Run Types for HiSeq v4 Chemistry
The following table shows types of sequencing runs and the number of possible cycles for each read when
using HiSeq v4 chemistry. Reference this information when setting up the run.
