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 Sequencing 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. 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.
