Custom primer requirements for the Illumina DNA PCR Free Prep, Tagmentation kit
Illumina DNA PCR-Free Prep, Tagmentation libraries require custom sequencing primers for successful sequencing on Illumina platforms because these libraries use novel chemistry. Failure to use the specified custom sequencing primers for these libraries results in sequencing failure on Illumina instruments. This article reviews the custom sequencing primer kit contents, custom primer loading volume and position requirements per instrument, and how to set up runs using custom sequencing primers.
The custom sequencing primers, sold separately, are provided at final concentration and require no further dilution. They are loaded into the dedicated custom primer wells, rather than spiked into the Illumina primer wells. For full instructions, refer to the Custom Primers Guide or Product Documentation for the respective instrument, listed in the “Resources” section of this article.
These custom sequencing primers are compatible with Illumina DNA PCR-Free libraries, PhiX control library (Cat. No. FC-110-3001), and all currently supported/compatible Illumina libraries.
The required custom sequencing primers are sold separately from the Illumina DNA PCR-Free library preparation kit.
Illumina DNA PCR-Free Prep Sequencing Primers Read 1 + Index 2 (Cat. No. 20041797)
Contains VP10 Custom Read 1 Primer (2 tubes X 7.5 ml) and VP14 Custom Index 2 Primer (2 tubes X 10.5 ml).
Please note that the VP14 Custom Index 2 Primer is not used on all instruments.
Custom primer loading volume and position requirements per instrument:
a. Requires iSeq 100 Control Software v3.0 or higher. Custom primers workflow must be enabled and primers added sequentially. See iSeq 100 Sequencing System Guide for further instructions. b. Requires NextSeq 1000/2000 Control Software v1.2 or higher and v3 flow cells. c. Primers required for sequencing Illumina DNA PCR-Free, Tagmentation libraries are contained in NextSeq 1000/2000 XLEAP cartridges, which require NextSeq 1000/2000 Control Software v1.7 or higher, and DRAGEN 4.2 d. Primers required for sequencing Illumina DNA PCR-free Prep, Tagmentation libraries are contained in NovaSeq v1.5 SBS cartridges, which require NovaSeq Control Software v1.7 or higher, and in NovaSeq X cartridges.
* See the MiniSeq (MNCS v2)/NextSeq 500/550 (NCS v4) Local Run Manager library prep kit definition file for Illumina DNA PCR-Free libraries with IDT for Illumina DNA/RNA UD Indexes or for Illumina DNA/RNA UD Indexes and steps to import as custom library. ** MiSeq (MCS > v3.0) Local Run Manager library prep kit definition file for Illumina DNA PCR-Free libraries with IDT for Illumina DNA/RNA UD Indexes or for Illumina DNA/RNA UD Indexes and steps to import as custom library. a. Leave “Denature and Dilute Onboard” box checked. For more details on appropriate well selection, please see the NextSeq 1000 and 2000 Custom Primers Guide. b. Read length is limited by the number of SBS cycles available in reagent kits, maximum read length for Illumina sequencing platforms, and 10 bp dual indexes. c. IEM sample sheet creation is required only for MiSeq run setup. IEM can create sample sheets for demultiplexing purposes for other instruments. d.Recommend run setup in LRM or standalone mode.
