Benefits of Methylation Analysis
DNA methylation analysis can help researchers gain valuable insight into gene regulation and identify potential biomarkers. Aberrant DNA methylation has been implicated in many disease processes, including cancer, obesity, and addiction. DNA methylation is also a common subject of agrigenomic investigations into responses to drought, temperature extremes, and other environmental changes.
High-throughput technologies such as next-generation sequencing (NGS) and microarrays enable genome-wide methylation profiling studies. These technologies offer new ways to understand the significance of DNA methylation, providing novel insights into the functional consequences of variation.
Key DNA Methylation Analysis Methods
Methylation Sequencing with NGSNGS enables comprehensive profiling of methylation patterns at single-base resolution across the whole genome, or in targeted epigenetic regions of interest. |
Methylation MicroarraysArrays enable quantitative interrogation of selected methylation sites across the genome, offering high-throughput capabilities that minimize the cost per sample. |
