Product Info
Bisulfite seq is a well know technology to detect DNA methylation and several technologies such as WGBS, RRBS, MeDIP-Seq, and MSBS are used for whole genome DNA methylation analysis. DNA methylation is important for regulation of cell development, differentiation and gene expression in molecular biology, genetics and epigenetics. Most methylated cytosines are found at CpG sites, and 70-80% of cytosines are methylated. The number of CpG sites in human genome is around 28 million, which is less than 1% of the genome compared with 4.4% expected.
Whole genome bisulfite sequencing (WGBS) is the most effective method of DNA methylation analysis. The only limitation is the sequencing cost is very high because the whole genome is sequenced including all the non-methylated regions.
Reduced Representation Bisulfite Sequencing (RRBS) is the reduced representation of a smaller fraction of the methylated CpG sites. RRBS combines restriction enzyme digestion and bisulfite sequencing, and enriches the sequencing for methylated CpG sites. It is an efficient technology for estimate the whole genome methylation patterns at the single base level. Although this allows a higher coverage depth and reduces the sequencing cost, the limitation is only 10% of the methylated CpG sites are covered.
Methylated DNA Immunoprecipitation Sequencing (MeDIP-Seq) is another whole genome enrichment technique used for selection of methylated DNA. Using antibodies against 5-methylcytosine, methylated DNA is enriched from whole genomic DNA via immunoprecipitation. 5-methylcytosine antibodies are incubated with fragmented genomic DNA and precipitated, followed by DNA purification and sequencing. There are several drawbacks of MeDIP-Seq: 1. Low resolution (150~200 bp) as opposed to the single base resolution; 2. Non-specific interaction due to antibody specificity and selectivity. 3. Bias towards hypermethylated regions.
The Methylation Specific Bisulfite Seq (MSBS) Library Prep Kit (illumina platform) was developed for construction of NGS libraries for methylated CpG sites using bisulfite treated DNA (20 ng – 500 ng) as input. The kit enriches methylated CpG regions, thus significantly reduce the sequencing cost. The kit estimates the whole genome methylation patterns at the single base level since it is based on a bisulfite-seq technology.
It is known that bisulfite treatment of completed NGS libraries causes tremendous damage to the libraries. By using bisulfite treated DNA as input, the kit overcomes the significant library loss due to the bisulfite conversion. The kit contains a mixture of PCR polymerases that have high-fidelity amplification and uracil tolerance which is ideal for bisulfite treated DNA.
Methylation Specific Bisulfite Seq Library Prep Kit Workflow
Three index types are available for the kit:
Non-index (Cat.# 30101): Libraries do not have index.
Index (Cat.# 30102): Each primer contains a unique barcode sequence of 6 bases to identify the individual library. Library multiplexing capacity is up to 48 samples. Index information can be downloaded here.
Unique dual index (Cat.# 30103): The multiplexing of bisulfite sequencing library is up to 96 samples with unique dual indexes. We used a Four-Base Difference Index System to generate indexes that have at least 4 bases different from each other in the 8-base index. The index primers remove NGS errors including index cross-contamination, index hopping, reads mis-assignment etc. Index information can be downloaded here.

Low methylation region in human genome.
Sequencing setting: Single-end 35 cycles (Read 1, 35 bases) recommended To maximize the methylated CpG enrichment, we recommend to sequence the MSBS libraries with single end 35 cycles (read1, 35 bases). This is because the enriched methylated CpG sites are mainly located around the beginning of read 1 sequences. Shorter single end reads tend to have better methylated CpG enrichment.

Vibrio cholerae is a comma-shaped, gram-negative bacterium. It is the cause of cholera in humans, which affects the upper small intestine. Transmission of the disease is mainly through contaminated food or water. Human subjects affected by cholera exhibit severe watery diarrhea and vomiting, caused by the cholera toxin produced by the bacterium. Many cases of cholera are life-threatening, as diarrhea and associated vomiting can lead to rapid dehydration and electrolyte loss. Even with the extensive research on its epidemiology, cholera still affects over 5 million people per year worldwide.

Storage Conditions and Product Stability All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.

Norgen’s microScript microRNA cDNA Synthesis Kit is an all-in-one, ready-to-use product for the reverse transcription of microRNA from either Total RNA preparations or enriched microRNA preparations. The kit contains the 2x Reaction Mix and the microScript microRNA Enzyme Mix. The kit utilizes Norgen’s microScript Reverse Transcriptase, a mutant version of Moloney Murine Leukemia Virus (M-MuLV) Reverse Transcriptase. It has reduced RNase H activity and increased thermal stability.
The workflow of Norgen’s microScript microRNA cDNA Synthesis Kit involves a simple, single-tube set-up by the mixing of 2x Reaction Mix, Enzyme Mix and the RNA template. The reaction can then be carried out in a thermocycler. A poly (A) tail is first added to the RNA template, followed by cDNA synthesis using an adapter primer. In addition to the ease-of-use, the single-tube set-up provides superb consistency and sensitivity. The cDNA could be used in a PCR or qPCR amplification using a Universal PCR Reverse Primer and the forward primer that contains the sequence of the microRNA of interest. A single cDNA preparation could be used for PCR amplification of a number of different microRNAs. In addition, the cDNA preparation could be used for PCR or qPCR detection (using gene-specific forward and reverse primers) of mRNA or large RNA if total RNA preparation was the starting template. This could allow for parallel evaluation of expression level of microRNAs and microRNA-targets.
