Service Details
Description of Genome Methylation Sequencing Services
    abm is offering a new RRBS service, allowing researchers to look at epigenetic alterations; those that do not affect the genetic code, but still alter transcriptional levels of genes. For examining DNA methylation, ABM employs the methodology of reduced representation bisulphite treatment. This technique uses the MspI restriction enzyme to cut at CCGG sites in the genome, size selection to purify these mid-size fragments with a higher CpG content, and bisulphite treatment which converts cytosine nucleotides in the genetic code to uracil while leaving 5-methylcytosine untouched. The combination of these techniques allows researchers to compare replicate samples where one sample has been treated to look for SNV’s of CT, which indicate the location of non-methylated cytosines. As a result of the use of the MspI enzyme, scientists can evaluate the epigenome at a fraction of the cost and sequencing power required by whole genome bisulphite sequencing (WGBS). Genomic DNA from either high quality or low quality samples, such as FFPE, can be used as input for this service.     abm also offers options for MeDIP-Seq. This technique uses an anti-5-methylcytosine antibody to select for genomic fragments that are methylated. These fragments are then sequenced and the coverage of these reads can be used to estimate the methylation level of the region that they map to. A genome browser such as IGV can also be used to visualize the data. ABM also offers bioinformatics analysis of this data in the form of the tool BATMAN (Bayesian tool for methylation analysis), which can estimate absolute methylation levels from data generated by MeDIP by modeling the density of methylated CpG sites.

Key features for abm's RRBS-Seq and MeDIP-Seq services:
  • Identification of the majority of methylated CpG sites at a fraction of the cost of WGBS.
  • MeDIP-Sequencing of methylated fragments allows researchers to focus on those areas exclusively.
  • Bioinformatics analysis from cutting edge tools allows researchers to draw powerful conclusions from sequencing data.
  • Guaranteed, high-quality data read-out of sample(s).
  • Strandedness is preserved.

Included in RRBS-Seq and MeDIP-Seq services:
  • Library Preparation.
  • RRBS-Seq bioinformatics analysis through standard WGS alignment and Bismark program.
  • MeDIP Bioinformatics analysis through BATMAN, which outputs absolute methylation levels.
  • QC (RSeQC/FastQC).
  • 3 months FREE storage of raw data.

Project Design/Advice
    Please email us at for assistance with starting your Genome Methylation Sequencing project or any inquiries about our next generation sequencing services. We offer discounts on bulk sample sequencing, please inquire for more details. ABM also provides an RNA purification service from original tissue samples for $50/sample. The minimum amount of RNA needed depends on the specific RNA preparation method pertinent for each project. A sample preparation guide for RNA Sequencing with ABM can be downloaded here.
    Our goal is always to deliver high-quality useful data to aid you in your research. We perform extensive maintenance and quality assurance on our equipment and strict quality control of samples throughout the sequencing process.However, next-generation sequencing by nature does not always deliver equally robust results due to a variety of factors, such as the variability inherent in the library preparation process, the biochemistry that takes place during sequencing and the quality of samples that we receive. We will make every effort to deliver the number of reads that are listed, although it is not possible to guarantee that those targets will always be achieved. The actual number of reads passing filter may vary by up to 10% from the listed target. Studies by various institutes have shown that there is minimal difference in coverage for 10% variation in reads past 5-10 million total reads.

Submit a new question:
Is your company certified as a service provider for Illumina sequencing?
Yes, we are a certified Illumina service provider.
What kind of analysis software do you use for sequence analysis?
The Illumina sequencers come with the integrated software that can perform the regular bioinformatics analysis functions. In addition, we have extensive experience with other open access software such as Galaxy, Adnuril, BioBike, etc. In other words, we are willing to perform additional bioinformatics analysis with different software and tools to satisfy a variety of demands from our customers.
What kind of QC methods do you adopt for the customer's sample(s)?
We will perform QC on your Total RNA samples prior to sequencing them, using the Agilent Bioanalyzer (industry standard) to determine the RNA Integrity Number (RIN). If the RIN is lower than 8, we consider these samples as having failed QC. If the samples do not pass QC, we will ask you to send us new samples. If we do not receive new samples, thereby cancelling the sequencing order, there will be a QC fee of $50/sample. This fee will be waived if you choose to continue with the sequencing order. A strict positive and negative control will be applied to this QC process.

The library QC will also be performed using the Agilent Bioanalyzer to determine library size and purity. Also, prior to loading the libraries on the sequencer, we perform qPCR quantification. The cost for this is included in the sequencing service.

For the QC of the final data from our sequencing service, the integrated software will generally do the job and provide adequate QC information, however, we can also provide additional QC data such as FASTQC upon request.

The data we output will pass our Q30 filter, which means that the error rate in base calls is less than 1 in 1000, or 0.1%. We will get a percentage at the end of the run which states the percentage of bases that have a Q score > 30, and this percentage is usually ≥85%.
What is the lead time for your WGS, WES, and RNA-Seq services?
Our sequencing lead times depend on workload, but are typically 2-4 weeks for sequencing data + 2-3 weeks for standard analysis. Please inquire for lead times for more detailed analysis.
Can you recommend any preferred RNA/DNA isolation kits to provide the best quality samples for these services?
For miRNA sequencing, you may isolate your RNA sample with a mirVana™ miRNA Isolation Kit,
mirVana™ PARIS™ Kit or PureLink® miRNA Isolation kit to enable adequate enrichment of your sample. If preferred, it should be okay to use Qiagen's kit, as long as the RNA Integrity Number (RIN) of the sample is above 8.0 to make sure there is no significant degradation. (Samples with a RIN lower than 8.0 may contain smaller degraded RNA fragments that can be sequenced in addition to the miRNAs). We prefer receiving Total RNA sample however so we can perform the bioanalyzer QC to check the RNA quality before beginning library construction. There will be no extra-charges if you submit Total RNA instead of isolated miRNA.

For miRNA sequencing we require 200ng-2ug of total RNA in 10ul of nuclease free water, as quantified with a fluorometric method. Lower amounts might result in inefficient ligation and low yield. If you are supplying purified miRNA, please submit a minimum of 50-100 ng of purified small RNA in 10ul is required. Purified small RNAs must be in nuclease free water or 10 mM Tris-HCI, pH 8.5.

For other services, there are generally no preferred DNA/RNA isolation kits as long as minimum requirements for QC are met.

Do I need any special software to view the data report files?
You will first need to unzip the fastq.gz files with winrar to view with vim, nano, gedit, Notepad plus plus. Nextgen workbench generally can view the data immediately without unzipping.

The RNASeq_sample_cufflinks_output.tar.gz will also need to be unzipped to see the text files by vim, nano, gedit, or Notepad plus plus. The unzipped data an also be imported as text into the data tab of Excel 2007. Other versions may differ.

To analyze further, Excel can sort, filter, find, match, etc and has many functions for conditional coloring, graphing, etc.
For the data, why are there no "ALT", "POS" and "ID" in your CSV file?
CSV files are meant to be used in conjunction with the raw fastq/bam files by certain commercial bioinformatics software. Many have a proprietary algorithms that takes the ALT POS and ID from the Fastq and indexes them for its own use. They are not meant to be used alone.
Would you let me know the description for the following: Genotype Sample_0, Coverage Sample_0, Coverage By Allele Sample_0, Variant Quality Sample_0, and Genotype Quality Sample_0?
Genotype (Sample Name) = nucleotide. Coverage (Sample Name) = will fail if there are insufficient reads. Coverage by allele (Sample Name) = will fail on one strand (+/-) read if only one side of the pair was sequenced. Variant Quality (Sample Name) = confidence of variant called. Genotype Quality (Sample Name) = confidence of genotype sequenced.
Concerning the column of "CHROM", would you let me know the rules of naming?
type of accession number| actual number| type of sequence| actual curated version used
Does your NGS service including RNA isolation?
We do not provide RNA isolation service by default. However we can provide this service. For more information, please refer to Cat#IR19001.
How many biological replicates do I need for each condition?
To increase confidence and reduce experimental error it is suggested that you submit at least 3 replicates per sample. Note that this is to serve as a guideline only and the final number of replicates and samples is to be determined by the end user based on their final experimental conditions.
