Methylation-Specific PCR Services for Aging Research


Aging is a complex biological process that involves a myriad of genetic and environmental factors, leading to alterations in DNA methylation patterns. Methylation-specific PCR (MSP) is a specialized technique that enables the detection and quantification of DNA methylation patterns in CpG islands, providing valuable insights into the epigenetic changes associated with aging. For performing MSP, DNA is modified by PCR performed with two primer pairs, which are detectable methylated and unmethylated DNA, respectively. MSP is a rapid measure for assession of the methylation status in CpG island.

Workflow of Methylation-Specific PCR in Aging Research

Our workflow of MSP encompasses several crucial steps, each contributing to the specificity of the methylation analysis.

  • DNA extraction. We begin with DNA extraction from the sample of aging or aging-related diseases. High-quality and intact DNA is essential to ensure reliable methylation analysis.
  • Bisulfite conversion. We perform bisulfite treatment for extracted DNA, during which unmethylated cytosines are converted to uracil, while methylated cytosines remain unaltered. Our chemical conversion services are crucial for distinguishing between methylated and unmethylated DNA sequences.
  • PCR amplification. Following bisulfite conversion, we employ PCR amplification using methylation-specific primers. These primers are designed to specifically target regions of interest that contain methylated DNA sequences. The amplification step allows for the selective amplification of methylated DNA, enabling the detection and quantification of DNA methylation at specific loci.
  • Analysis of amplified products. We then analyze the amplified products from the PCR using gel electrophoresis or quantitative techniques. Gel electrophoresis can visualize the presence or absence of methylated DNA based on the size or intensity of the DNA bands. Quantitative methods, such as real-time PCR, provide quantification of DNA methylation levels at specific CpG sites.
