When ordering your myBaits kit, please indicate the sequencing library configuration you intend to enrich. The standard adapter blocking reagent provided with the kit (Block X) is compatible with Illumina® TruSeq®-style or Nextera®-style libraries with single 6-12 bp or dual 6-12 bp indexing. These options cover the vast majority of currently available commercial library preparation systems intended for sequencing on any Illumina platform.

For different adapter configurations than those described above, we recommend ordering Custom IDT® xGen® Blocking Oligos. At a concentration of 1 μg/μL, custom adapter-blocking oligos can be used in lieu of myBaits Block X.
If you are not certain, or later decide to change your library prep kit, please contact us so we can instruct you on how to obtain the correct blocking oligos.
