The rapid development of 5-hydroxymethylcytosine (5hmC) assays could guide studies of other nucleotide variants, particularly 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC), which have been recently identified in mammalian DNA. In order to better quantify the global levels of 5-methylcytosine (5mC) oxidation derivatives, mass spectrometry (MS)-based methods have been developed. A more accurate method for quantifying low levels of modified nucleotides is liquid chromatography (LC)-mass spectroscopy (MS), which separates and identifies hydrolyzed nucleotides. By combining LC with high-resolution MS and using isotope-labeled internal standard to improve the detection limits and allow for accurate quantification of rare base modifications.

EpigenHub provides customers with global DNA 5fC/5caC quantification service, which is highly accurate and sensitive, independent of DNA quality and sequence. The measurement results reflect the absolute level of global rare base modifications, but it is not suitable to determine the precise location of these modifications.

Advantages of Choosing EpigenHub
