Zymo-Seq WGBS Library Kit


Zymo-Seq WGBS Library Kit단일 튜브에서 whole genome bisulfite (WGBS) library준비할 수 있는 유일한 키트입니다. Zymo-Seq WGBS Library Kittagmentation 기술을 적용하여 기존의 ligation 기반 라이브러리 준비 방식에서 요구되는 번거로운 단편화, 효소 처리 및 정제 단계를 없앴습니다. 이러한 간소화된 워크플로작업 시간을 최소화하여 고처리량 애플리케이션에 이상적입니다. Zymo-Seq WGBS Library준비하려면 먼저 손상되지 않은 genome DNAbisulfite 처리합니다. 그런 다음 (1) 2차 가닥 합성, (2) tagmentation통한 adapterization, (3) 라이브러리 증폭 및 indexing세 가지 라이브러리 준비 과정을 단일 튜브에서 완료합니다. 정제 후, 라이브러리는 Illumina 기기에서 Sequencing할 준비가 됩니다.

WGBS는 모든 cytosine대한 염기 수준의 메틸화 정량화를 제공하므로 DNA 메틸화 연구의 표준으로 여겨집니다. Zymo-Seq WGBS Library Kit모든 종의 CG, CHG CHH 부위의 whole-genome methylation 분석에 이상적입니다. Zymo-Seq Library사용하면 사람과 마우스의 CpG 부위 중 90% 이상을 검출할 수 있습니다.

Technical Specifications




Zymo-Seq WGBS Library Prep Workflow

Enzymatic reactions are consolidated in a single tube to minimize hands-on time. Intact genomic DNA is first bisulfite converted, which then undergoes second strand synthesis (1). Tagmentation is added directly to the reaction to tag adapters onto the double-stranded DNA (2). Indexing primers and PCR mixture are added to amplify the WGBS library (3). Purified libraries are ready for sequencing on Illumina instruments.



Consistent Library Preparation to Maximize Sequencing Data

Zymo-Seq libraries provide longer, useable reads by reducing library preparation bias as found in conventional libraries. Unbiased libraries will have constant methylation levels across the entire read length. Conventional methods typically require an end-repair step and artificial nucleotides incorporation, which require additional trimmings to reduce methylation bias. Mouse and Arabidopsis WGBS data were generated using the Zymo-Seq kit (left) and compared to publicly available data of WGBS libraries prepared using the conventional method (right). All sequencing reads were first trimmed and then aligned using Bismark. The M-bias plots shown above were generated by plotting the average CpG methylation level across each position of the mapped read.


Reproducible Coverage and Methylation Detection

Coverage is preserved using as little as 10ng DNA input. Over 93% of genomic CpG sites overlapped (10X depth cutoff) between Zymo-Seq libraries prepared using 100ng and 10ng of Arabidopsis genomic DNA. The two libraries had less than a 10% methylation difference in over 90% of shared CpG sites, demonstrating consistency between different inputs.

 

Unbiased methylation callings are produced using Zymo-Seq library preparation. Spike-ins with known methylation ratios (0%, 10%, 25%, 50%, 75%, and 100%) were added to 100ng of genomic DNA prior to processing with the Zymo-Seq WGBS Library Kit or using the conventional methodology. The observed methylation % for Zymo-Seq libraries closely matched theoretical methylation levels (R2 = 0.997).
