Eliminate the Need for Amplification

Amplifying AT or GC rich genomic regions often leads to sequence biased nucleotide compositions and poses a serious challenge during analysis. Using specially designed master-mixed enzymes, the NEXTFLEX® PCR-Free DNA Library Prep Kit completely eliminates the need for amplification, enabling better read mapping and a reduction in duplicate sequences, leading to reduced sequence cost and bias, for more representative base identities and better de novo assembly.

In addition, the NEXTFLEX® PCR-Free DNA Sequencing Kit features patent pending Enhanced Adapter Ligation Technology, resulting in library preps with a larger number of unique sequencing reads. With these improvements to the ligation enzymatic mix, the user will now have the ability to perform ligations with longer adapters, and can expect to see better binding efficiencies. The NEXTFLEX® PCR-Free Sequencing Kit simplifies workflow by using master mixed reagents and magnetic bead based cleanup, reducing pipetting and eliminating time consuming steps in library preparation.

Exceptional Multiplexing Capabilities

Using the NEXTFLEX® PCR-Free Barcodes, the user can index 6, 12, 24, or 48 samples at once providing exceptional sequencing capacity.

The NEXTFLEX® PCR-Free DNA Sequencing Kit is designed to prepare gel-free libraries using magnetic bead based size selection from as little as 500 ng of input DNA. If you have specific insert size requirements and would like to perform agarose gel size selection, we recommend the NEXTFLEX® Agarose Gel Size Selection Kit.

Automation Solutions

The NEXTFLEX® PCR-Free DNA Sequencing Kit and NEXTFLEX® PCR-Free Modules are automated on the Tecan Freedom EVO Workstation. For more information about this customer developed automation solution read Tecan’s article, GeT with the NGS program, published in the Tecan Journal.

For larger volume requirements, customization and bulk packaging is available. For increased flexibility individual reagents (non-master mixed) are also available. Please contact Bioo.NGS@perkinelmer.com for further information.

How should PCR-free libraries be quantified?
PCR-free libraries should be quantified using qPCR. qPCR quantification is necessary because the final library will have a mixture of doubly-ligated, singly-ligated, and unligated products, and only the doubly-ligated products will be able to generate clusters efficiently on the flow cell.

What sequencing platforms is this kit compatible with?
This kit is compatible with all common Illumina® sequencing platforms including HiSeq®, MiSeq®, and NextSeq® 500 systems.

How many barcodes (indices) are available for the NEXTFLEX® PCR-Free kit?
48 barcodes are available as NEXTFLEX® PCR-Free Barcodes. For input amounts of 1 µg or less NEXTFLEX-96 DNA Barcodes may be used instead, which have 96 available barcodes.

My library does not run as expected on a gel or Agilent® Bioanalyzer®. Why is this?
The Y-shaped nature of unamplified barcoded adapters often causes products to migrate at a slightly higher molecular weight than expected. This is normal and should not affect the performance of the libraries.

The NEXTFLEX® PCR-Free DNA Sequencing Kits contain the reagents to prepare 8 or 48 genomic DNA samples (0.5 – 3 µg) for Illumina®-compatible next-generation sequencing. The shelf life of all reagents is 12 months when stored properly at -20°C. Ships on dry ice.
