What is bisulfite conversion used for?

What is bisulfite conversion used for?

Bisulfite modification of DNA is the most commonly used, “gold standard” method for DNA methylation studies providing single nucleotide resolution. This technology is based on the chemical conversion of unmethylated cytosine to uracil.

How do you quantify bisulfite-converted DNA?

Quantification of Bisulfite-Converted DNA Converted DNA should be quantitated as RNA using a UV spectrophotometer (NanoDrop) with Ab260 nm 1.0 = 40 µg/ml.

Is bisulfite-converted DNA single stranded?

Uracil is then converted to thymine upon PCR amplification. Note that bisulfite-converted DNA is a single-stranded DNA because the two strands of DNA are no longer complementary after conversion.

How do you do bisulfite sequencing?

Bisulfite sequencing relies on the conversion of every single unmethylated cytosine residue to uracil. If conversion is incomplete, the subsequent analysis will incorrectly interpret the unconverted unmethylated cytosines as methylated cytosines, resulting in false positive results for methylation.

What can we measure with next generation sequencing?

For example, NGS allows labs to:

  • Rapidly sequence whole genomes.
  • Deeply sequence target regions.
  • Utilize RNA sequencing (RNA-Seq) to discover novel RNA variants and splice sites, or quantify mRNAs for gene expression analysis.
  • Analyze epigenetic factors such as genome-wide DNA methylation and DNA-protein interactions.

How much does whole genome bisulfite sequencing cost?


Bulk Epigenomics Library Preparation Internal (WCM, WCM Qatar & Cornell U)
WGBS (Whole Genome Bisulfite Sequencing) $250
ChIP-seq $150
ATACseq (library prep from cells) $225
ATACseq partial (price per sample) $100

What is the principle of Methylation Specific PCR?

Methylation-specific PCR (MS-PCR or MSP) is one of the most commonly used methods for gene/sequence-specific detection of DNA methylation. The DNA undergoes bisulfite conversion of cytosine to uracil and then the methylated sequences are selectively amplified with primers specific for methylation.

Can a bisulfite conversion kit be used in blood?

A complete and reliable bisulfite conversion kit that eliminates cumbersome DNA precipitation steps and allows DNA bisulfite conversion directly from blood, tissue, and cells without prior DNA purification. EZ DNA Methylation-Gold

What do you need to know about DNA bisulfite conversion?

A Researcher’s Guide to Successful DNA Bisulfite Conversion | What is Epigenetics? DNA bisulfite conversion is a unique tool used to discriminate between methylated and unmethylated cytosines for DNA methylation studies.

Which is the best bisulfite conversion kit for methylation?

These bisulfite conversion kits are recommended with Illumina’s Infinium® Human Methylation 450K and MethylationEPIC Kits. Zymo Research has the best bisulfite conversion kits selection available, featuring streamlined workflows, ≥ 99% conversion rates, and low elution volumes for concentrated, bisulfite-converted DNA.

How is the conversion of bisulfite to uracil performed?

Bisulfite conversion involves the deamination of unmodified cytosines to uracil, leaving the modified bases 5-mC and 5-hmC. This procedure can then be followed either by PCR amplification or massively parallel sequencing methods to reveal the methylation status of every cytosine in gene specific amplification or whole genome amplification.
