FAQ: What additional reagents do I need to complete the Ultra II FS DNA PCR-free workflow?

In addition to the NEBNext Ultra II FS DNA PCR-free Library Prep Kit, you will need the NEBNext Multiplex Oligos for Illumina (Unique Dual Index UMI Adaptors DNA Set 1) (NEB #E7395) to complete the workflow. Please be aware that all other oligos from NEB are not compatible with the PCR-free workflow.
