Illumina DNA Prep and Illumina DNA PCR-Free Prep are available. These library prep solutions offer improved performance while reducing turnaround time and hands-on time compared to TruSeq DNA Nano.
TruSeq DNA Nano enables efficient interrogation of samples with limited available DNA. Based on mechanical fragmentation–ligation chemistry, this low-input method delivers high coverage quality and reduced bias for virtually any sequencing application.
TruSeq DNA Nano has been streamlined by replacing gel-based size selection with bead-based selection, enabling researchers to prepare high-quality libraries in less than a day. It is optimized for a variety of read lengths, from 2 × 101 bp to 2 × 151 bp.
TruSeq DNA Nano offers excellent results with as little as 100 ng input, eliminating the typical requirement for micrograms of DNA. This enables researchers to study samples with limited available DNA (eg, tumor samples) and helps preserve samples for use in future or alternate studies. In addition to accelerating the workflow, bead-based size selection avoids typical sample loss associated with gel-based selection.
TruSeq DNA Nano reduces the number and average size of typical PCR-induced gaps in coverage. The enhanced workflow reduces library bias and improves coverage uniformity across the genome. These kits also provide excellent coverage of traditionally challenging genomic content, including GC-rich regions, promoters, and repetitive regions. This enables researchers to access more information from each sequencing run. Truseq DNA Nano products are validated for high-quality genomic coverage for virtually any next-generation sequencing application.
