C. elegans 6mA Quantification by UHPLC-MRM-MS

Previous studies have demonstrated that 6mA is broadly distributed across the genome of C. elegans. Among these advanced and sensitive detection techniques, ultra-performance liquid chromatography-electrospray ionization tandem mass spectrometry in multiple reactions monitoring (MRM) mode (UPLC-MRM MS) analysis occupies an important position. As an antibody-independent approach, UHPLC-MRM-MS is sensitive, highly specific and very fast. It can detect 6mA at a relatively low level. During the procedure, the result is susceptible to sample contamination.

DNA methylation levels in the genome alter in the context of specific developmental and pathological states. To reveal the specific mechanism of these processes in the model organism C. elegans, an accurate assay for fast and reliable quantifying of 6mA is required.

Properties and advantages of UHPLC-MRM-MS

  • Higher separation efficiency, faster chromatography, enhanced chromatographic resolution and less solvent consumption compared to classical HPLC.
  • MRM functions can be overlapped, providing selectivity even on coeluted compounds under fast chromatography conditions.
  • The sensitive and highly specific method allows a simple and fast sample preparation with no prior purification.
