摘要: Next-generation DNA sequencing (NGS) offers many benefits, but major factors limiting NGS include reducing the time and costs associated with: 1) start-up (i.e., doing for first time), 2) buy-in getting any data from a run), 3) sample preparation. Although researchers have focused on preparation costs, few addressed two problems. Here, we present iTru iNext, dual-indexing systems Illumina libraries that help address all three of these issues. By breaking library construction process into re-usable, combinatorial components, achieve low start-up, buy-in, per-sample while simultaneously increasing number samples can be combined within single run. We accomplish this by extending TruSeq approach 20 (8+12) indexed adapters produce 96 (8x12) unique combinations to 579 (192+387) primers 74,304 (192x387) combinations. synthesized 208 validation, 206 them passed our validation criteria (99% success). also used create hundreds in variety scenarios. Our reduces requiring only one universal adapter which works with PCR uniquely identify samples. because: relatively oligonucleotides are needed large libraries; possible allows use primer sets different projects, facilitates pooling during sequencing. methods highly customizable, resulting standard demultiplexed software packages, thereby minimizing instrument customization headaches. In subsequent Adapterama papers, same stubs construct double- quadruple-indexed amplicon double-digest restriction-site (RAD) libraries. For additional details updates, please see http://baddna.org.
