Global DNA 5hmC Quantification by LC-MS/MS


Liquid chromatography tandem mass spectrometry/mass spectrometry (LC-MS/MS) provides absolute measures of 5hmC content in genomic DNA. It’s highly accurate and sensitive and is regarded as the ‘gold standard’ for global DNA hydroxymethylation measurement. Creative BioMart provides customers with a global DNA 5hmC quantification service with solid expertise and state-of-the-art LC-MS/MS equipment.

What Is LC-MS/MS for Global DNA 5hmC Quantification?

In this assay, genomic DNA is enzymatically digested into normal and modified mononucleotides, which are then separated by high performance liquid chromatography (HPLC) and then detected by the mass spectrometer. Due to the efficient separation provided by HPLC and structure-based mass spectrometry, LC-MS/MS can perform specific and sensitive detection of various modifications of DNA. Recently developed methods based on changes in liquid chromatography technology, such as liquid chromatography electrospray ionization tandem mass spectrometry with multiple reaction monitoring (LC-ESI-MS/MS-MRM), have pushed the limits of epigenetic analysis and subsequently utilized to quantification of 5fC and 5caC in addition to 5mC and 5hmC.

Features of Global DNA 5hmC Quantification by LC-MS/MS

  1. Independent of DNA quality
  2. Extremely high sensitivity, specificity, and repeatability
  3. Independent of sequence, thus can be utilized to analyze DNA from various species
  4. The measurement results reflect the absolute level of global DNA hydroxymethylation and is not suitable for determining the precise location of the 5hmC modification
