DNA Methylation analyses

LUMA (LUminometric Methylation Assay)

  • Method for global DNA methylation analysis.
  • Quantification of the number of restriction enzyme cuts, based on methylation sensitivity.
  • Rapid & quantitative determination of methylation level.
  • No information about the location or repartition of DNA methylation.

MeDIP (Methylated DNA ImmunoPrécipitation)

  • Enrichment of fragmented genomic DNA using an antibody specific for 5mC
  • Low CpG dinucleotide density may not be accurately analyzed by MeDIP.
  • 5mC antibodies are capable of discrimination between 5-hmC and 5-mC.

Bisulfite Pyrosequencing

  • Analysis & quantification of the methylation degree of several CpG positions in close proximity.
  • Bisulfite-based methods cannot differentiate 5-mC and 5-hmC.

Histones Marks analyses

CUT & RUN (Cleavage Under Targets & Release Using Nuclease)

  • Powerful and versatile technique used for probing protein-DNA interactions within the natural chromatin context of the cell
  • CUT&RUN provides a rapid, robust with low cell number assay
  • Free from formaldehyde cross-linking, chromatin fragmentation, and immunoprecipitation, making it a more efficient method for identifying target genes.
