In addition to our standard Celero products, we offer customizable Celero solutions for high throughput DNA-seq, high throughput amplicon sequencing, and 384 multiplexing with NuQuant technology.
Please speak with an NGS Expert to find out more.
Celero EZ DNA-Seq provides an innovative solution to streamline whole genome sequencing (WGS) library preparation and quantification. This library prep kit features a fast, easy-to-use, addition-only workflow that eliminates post-ligation bead purification, resulting in faster library preparation and reduced hands-on time.
Celero EZ DNA-Seq features our enzymatic fragmentation technology that is simple, robust and consistent for fragmentation of genomic DNA into homologous sized fragments. This technology provides greatly improved fragmentation without optimization, outperforming standard DNA-Seq kits for a broad range of sample types and concentrations to provide the best possible starting material for your sequencing protocol.
DNA libraries from Celero EZ provide higher yields and better uniformity of coverage, ideal for downstream target enrichment applications like whole exome sequencing. When combined with Tecan’s DreamPrep™ NGS automation workflow, Celero EZ DNA-seq delivers a robust solution for high throughput WGS and target enrichment applications.
This library preparation kit is integrated with NuQuant®†, a proprietary library quantification method for efficient and accurate quantitation of Next-Generation Sequencing (NGS) libraries. The NuQuant method eliminates the need for time-consuming or inaccurate library quantification methods like qPCR, fluorometry (e.g. Qubit®) or microfluidic electrophoresis (e.g. Bioanalyzer®) allowing DNA-Seq libraries to be constructed and quantified in less than 3 hours.

Comparing DNA-Seq library preparation workflow of Celero Enzymatic with competitive kits. Celero has the least steps and is integrated with NuQuant library quantification method.
Celero Enzymatic Fragmentation with PCR workflow offers a simple and quick workflow for generating sequencing-ready quantified libraries.
NuQuant library quantification is a proprietary method by which fluorescent labels are incorporated into the library molecules during the library preparation process. Each library molecule has an equivalent number of labels incorporated, regardless of the size of the library fragment, resulting in a direct measurement of molar concentration using standard fluorometers. NGS library quantification with NuQuant is accurate, easy to use and is integrated with the Celero PCR Workflow with Enzymatic Fragmentation DNA-Seq library preparation kit.
Library quantification with the NuQuant method is more accurate than Bioanalyzer and qPCR.
NGS library quantification with NuQuant compared to Qubit, qPCR and Bioanalyzer.
Celero EZ is a streamlined library preparation solution with one-bead clean up step compared to traditional workflows enabling a more efficient complete downstream whole exome sequencing application.
The percentage of target coverage can be seen for the two kits tested. For the KAPA HyperPrep kit, coverage starts to drop off at high densities, becoming apparent at 10x, increasing at 20x, and dropping to <80 % at 50x. The Celero EZ DNA-Seq kit is able to consistently maintain greater than 98 % target coverage, which enables more accurate variant calling.
This figure shows a critical advantage of the Celero EZ DNA-Seq library preparation kit – the even coverage of target sequences. The KAPA HyperPrep kit offered insufficient coverage for large numbers of targets, while Celero libraries provided an even depth of coverage across all target sites

Celero EZ DNA-Seq includes all necessary buffers, primers and enzymes for library construction. SPRI purification beads and EvaGreen are not included.
Required equipment includes a microcentrifuge, pipettes, vortexer, a thermal cycler, a magnetic plate for 0.2 mL tubes, strips, or plates and a fluorometer. An Agilent Bioanalyzer or Fragment Analyzer may also be useful for optional analytical tests. A comprehensive list of required and recommended equipment can be found in Section II.B of the User Guide.
Celero EZ DNA-Seq is an end-to-end solution designed to generate libraries for Illumina sequencing starting from gDNA or cDNA and has not been tested with alternative library preparation systems.
We recommend a column-based extraction method, including: Qiagen QIAprep Miniprep or DNeasy Miniprep kits, Zymo Quick-DNA kits and Thermo Fisher PureLink Genomic DNA kits.
We do not recommend the use of these methods as any carryover of organics may inhibit downstream enzyme activity. If using, we recommend using a column-based purification of the downstream enzyme activity. If using, we recommend using a column-based purification of the DNA prior to input into the kit.
Celero EZ DNA-Seq has been designed for use with a broad range of different organisms. Special consideration should be given when using low-input samples from organisms with large genomes.
This kit is designed for use with DNA samples of high molecular weight with little or no evidence of degradation. We strongly recommend using high quality DNA with a A260:A280 ratio in excess of 1.8 and A260:A230 ratio in excess of 2.0. Use of DNA samples with lower ratios may result in low library yield.
A minimum amount of overage should be used in master mixes to ensure the full nominal number of reactions in the kit. The amount of overage needed depends on sample batch size, pipetting accuracy, and viscosity of reagents. We have found that 12-15% extra volume in the enzymatic fragmentation and adaptor ligation master mixes is sufficient for most experiments.
Yes.
The enzymatic fragmentation step is required in the Celero EZ-DNA-Seq workflow. For sample types that are already fragmented, Celero DNA-Seq (Part No. 0360) is available with optional mechanical (Covaris) fragmentation and End Repair.
No.
RNAClean XP beads are certified to be RNase and DNase free. We have tested both RNAClean XP and AMPure XP beads in our kits and observe no difference in performance between products.
Due to the large number of commercially available magnets, we do not have a comprehensive list of compatible products. However, many magnets are compatible. As long as the magnet is strong enough to clear the solution of magnetic beads, it can be applied to the system. We have the following guidelines for selecting a magnetic separation device:
Yes. Please contact Tecan NGS Technical Support for information on using NuQuant with previously frozen libraries.
We recommend using NuQuant to accurately quantify the final libraries for multiplex pooling. The final library pool concentration should be determined using a qPCR-based method before loading onto an Illumina sequencer. Please refer to section IV. F. in the User Guide for guidelines on library quantitative and qualitative assessments.
The adaptors add 136 bp to the library.
Celero EZ DNA-Seq libraries are compatible with Illumina sequencing platforms.
Please follow manufacturer’s recommendations for library QC, quantification, balancing and loading of the amplified library on the sequencer.
Celero EZ DNA-Seq libraries are designed for use with the standard Illumina sequencing primers for both single-end and paired-end sequencing applications.
Yes. The libraries produced using this kit can be used for both single-end and paired-end sequencing. Special consideration should be given to the expected insert size in the paired-end assay. The workflow generates libraries with an average insert size that is dependent on the fragmentation conditions used.
Each barcode is a minimum edit distance of 3 from any other barcode. This means that a minimum of three edits (replacement, insertion, or deletion) must occur before one barcode becomes a different barcode. For further details on the barcode design strategy, please refer to Faircloth BC, Glenn TC (2012), Not All Sequence Tags Are Created Equal: Designing and Validating Sequence Identification Tags Robust to Indels. PLoS ONE 7(8): e42543. doi:10.1371/journal.pone.0042543.
The final Celero EZ libraries can be analyzed using standard pipelines. To remove adaptor sequences use standard TruSeq sequences for read trimming.
