CD Genomics is providing a novel, flexible, and scalable genome-wide DNA methylation profiling method, MethylRAD, to allow for de novo methylation analysis with extremely low DNA input.

The Introduction of MethylRAD-Seq

ethylRAD uses methylated modified dependent endonuclease, such as FspEI, MspJI, LpnPI, AspBHI, etc., to recognize cytosine methylated on DNA and cut double chains at a distance downstream of the recognition site, and if the DNA double-strand has a central symmetric methylation state, a fixed length of double-strand DNA fragment can be cut and then sequenced. DNA methylation is a heritable epigenetic mark and plays a vital role in many biological processes such as embryogenesis, cellular differentiation, X-chromosome inactivation, genomic imprinting and transposon silencing, perturbed methylation patterns are sometimes a hallmark of important human diseases. Profiling the DNA methylation landscape and its dynamics enable researchers to look deeply into key epigenetic mechanisms that modulate development and diseases. MethylRAD allows for de novo (reference-free) methylation analysis, extremely low DNA input (e.g. 200 ng) and adjustment of tag density, all of which are still unattainable for most widely used methylation profiling methods such as RRBS and MeDIP.

Key Features and Advantages of MethylRAD-Seq

  • Extremely low amount of input DNA required
  • Adjustable tags density
  • High specificity, sensitivity and reproducibility
  • Allows for de novo methylation analysis
  • Ideally suited for large-scale methylation profiling
  • Comprehensive bioinformatics analysis
  • Suitable for most species especially plant species

MethylRAD-Seq Workflow

The MethylRAD-Seq Workflow is outlined as below:
