MGIEasy PCR-Free DNA Library Prep Set

MGIEasy PCR-Free Library Prep Set is specifically designed for making WGS libraries for MGI High-throughput Sequencing Platforms. This library prep set is optimized to convert 120-200 ng size selected fragmented DNA into a customized library. MGI WGS PCR-free library preparation, combined with MGI DNBSEQTM sequencer, is the true PCR-free NGS workflow without PCR amplification, resulting in no error accumulation and higher data accuracy.


Compatible with Multiple Species Types:  Compatible with human, animals, plants, bacteria, fungi etc., e.g. human (blood, saliva, fresh tissue), mice, rice, E.coli and metagenomics.
Fast, Simple and Automated Workflow:   Library preparation can be completed in 3.5 hours with size-selected DNA as input; the workflow is simple and suitable for automated library preparation without the risk of amplicon contamination.
No Amplification Error Accumulation:  By eliminating PCR amplification steps, WGS PCR-free prepared and sequenced by MGI DNBSEQTM platform has no amplification error accumulation, resulting in better genome fidelity.
Higher Coverage Uniformity:   Compared with traditional WGS (PCR amplification), WGS PCR-free reduces GC bias and improves coverage uniformity across the genome, such as GC-rich region, promoter and repetitive region.
Higher Performance of Variant Detection:  Compared with traditional WGS (PCR amplification), PCR-free WGS shows higher sensitivity and accuracy of variant detection, especially indels.
