Lotus DNA library prep kit

One kit. Flexible workflow. Endless applications.

One kit. Flexible workflow. Endless applications.

The Lotus DNA Library Prep Kit enables streamlined preparation of high-quality next generation sequencing (NGS) libraries from double-stranded DNA (dsDNA). The kit uses enzymatic fragmentation to generate libraries suitable for PCR-free, PCR-amplified, and targeted sequencing applications on Illumina platforms.

  • Get the uniform sample coverage you need without relying on expensive equipment
  • Regain valuable time with a fast, simple workflow
  • Create application-specific NGS libraries by adding IDT adapters and xGen products for target capture

The Lotus kit can be customized for your applications when combined with one of the many IDT adapter options (see Ordering section). Additionally, use of xGen hybridization capture products provides a complete NGS solution that takes you from sample preparation to sequencing.

Swift 2S Turbo DNA Library Kits come in two configurations:

2S Turbo: All-in-one for quick implementation

Whether discovering or screening germline mutations, 2S Turbo makes library prep more accessible to any laboratory. This kit configuration includes library prep reagents and Swift adapter compatible with several indexing options such a Single, Combinatorial Dual (up to 768-plex) or Unique Dual Indexing.

2S Turbo Flexible: Broaden the range. Expand your scale.

Need a powerful pipeline to detect any variant across any sample quality and quantity? Combine our 2S Turbo Flexible with your choice of full-length indexed adapters (e.g. Illumina TruSeq DNA Single Indexes and TruSeq DNA CD, etc..) to create a fast, efficient, and scalable workflow to detect both rare and common variants in any size project.

“Wanted to add, I am really impressed with the uniformity in the library size! Haven’t seen that ever with a transposase based library kit.”-From a Client in Maryland 

“We spoke a few weeks ago on a tech support call regarding using the Swift 2S Turbo Library Prep Kit on a mixed microbial plasmid DNA input. I wanted to let you know we followed the 10ng input parameters and it worked beautifully! Our final libraries were slightly large (~450-500bp) but still gave us high-quality sequencing reads and great data. Thank you for your help!”-Elinne Becket, Ph.D., Assistant Professor-Department of Biological Sciences, California State University, San Marcos

Accel-NGS 2S DNA library kits

The Accel-NGS 2S family of products employ a combination of unique fragment repair mechanisms and an exceptionally efficient adapter technology to generate the most diverse libraries for Illumina® platforms. The synergy in this process allows for processing DNA inputs as low as 10 pg while minimizing base composition bias in final libraries. All of the Accel-NGS 2S Kits permit for single-tube processing of just a few samples with a simple protocol while easily being automated for high-throughput labs.

The Accel-NGS 2S family is the best choice for users seeking the most versatile, highest performing library prep kit for double-stranded DNA inputs, including ChIP-Seq, cfDNA, and FFPE samples. Expand your capabilities, run those difficult samples, or add new services to a core lab. With the Accel-NGS 2S DNA Library Kits, you can expand your sequencing capability and construct libraries from limiting DNA samples.

Accel-NGS Methyl-Seq library kits

Low-input Methylation Sequencing

The Accel-NGS Methyl-Seq DNA Library prep utilizes Adaptase® technology for capturing single-stranded DNA molecules in an unbiased manner. As bisulfite treatment of samples damages DNA, Swift Biosciences’ single-strand compatible Adaptase technology maximizes recovery of DNA from bisulfite-converted samples. The resultant libraries accurately represent sample base composition of the entire genome for the analyzed organism. The technology has quickly become the gold standard for providing the most comprehensive coverage of the methylome. It is an excellent choice for whole genome bisulfite sequencing as well as targeted bisulfite sequencing applications, such as RRBS and hybridization capture using the NimbleGen™ SeqCap™ Epi Enrichment Sysem. The Accel-NGS Methyl-Seq Kit is also compatible with bisulfite-converted DNA samples enriched by ChIP or other methods. This library preparation technology contains a uracil tolerant polymerase which is ideal for sequencing ancient DNA samples that may contain uracil nucleotides as a result of damage.

Accel-NGS 1S DNA library kits

NGS DNA Library Construction from Samples with Limiting Amounts of Degraded DNA

The Accel-NGS 1S DNA Library Kits enable users to make libraries from the impossible. Libraries can be made from precious, damaged and degraded samples by using Swift’s Adaptase™ technology. Unlike other library methods, the Adaptase technology can generate library molecules from single-stranded DNA fragments, which allow researchers to recover more of their input DNA from difficult and rare samples compared to other commercially-available products-for Ilumina® NGS Platforms

The Accel-NGS 1S Library Kits will yield libraries in 2 hours from as little as 10 pg of input and fragments as short as 40 bp. The kits work with precious and difficult-to-use samples, such as single-stranded DNA, heat-denatured pathogenic samples (microbial DNA), viral DNA, first-strand cDNA, ancient DNA, ChIP-Seq, and degraded DNA from FFPE samples. Accel-NGS 1S Library Kits are the best choice for users needing to sequence treasured or difficult-to-process samples, which cannot be sequenced by other methods. Expand your research by processing precious, damaged and degraded samples on either the Illumina® or Ion Torrent™ NGS platforms.

“We choose the Swift 1S kit for construction of sequencing libraries when available sample is low, the quality is uncertain, or when we want to capture single stranded as well as double stranded DNA. We have found the kit easy to use with well labeled components and a straightforward protocol. We find that libraries rarely fail with this kit even when starting material is highly degraded. The availability of unique dual indexes is also key to allow sequencing on any available Illumina platform. With regards the samples from the NASA Twins study, we were most interested in being able to detect single-stranded DNA viruses as well as all other organisms as part of our shotgun metagenome sequencing project, and this drove the decision to use the Swift 1S kit.”

“I would like to give a summary that we tried to use a competitor’s kit first for our project but it ended up that we needed to do 17 PCR cycles to achieve the concentration of libraries that we needed. But what that meant was that there would be increased duplication rate when we did next-generation sequencing. With your Swift 1S we only needed to do 4-5 PCR cycles and our duplication rate was 7-13% when using HiSeq4000 for deep sequencing. We were interested in both ssDNA and dsDNA. We are happy with your product.”
