How much PhiX should I spike in to my library before sequencing?

How much PhiX should I spike in to my library before sequencing?

  • We recommend using the same recommendations as those for the NovaSeq 6000, as outlined in the user guide.  

 

Phi-X spike-in recommendations: 

  • NextSeq 1000/2000: 5% PhiX spike-in  
  • NextSeq 500/550: 5% PhiX spike-in  
  • NovaSeq 6000/X Plus: 
  • 5% PhiX spike-in when pooling with non-Seeker libraries 
  • 10% PhiX spike-in when sequencing only Seeker libraries
