DNA methylation, the addition of a methyl group to the cytosine residue in CpG dinucleotides, is a fundamental epigenetic modification that regulates gene expression and genome stability. Dysregulation of DNA methylation has been implicated in various diseases, including cancer, neurological disorders, and autoimmune diseases. Understanding the dynamics of DNA methylation is therefore critical for elucidating disease mechanisms and developing therapeutic interventions. Traditional methods for studying DNA methylation, such as bisulfite sequencing and methylation-specific PCR, have limitations in terms of sensitivity, specificity, and scalability. AffiZYME® Methylation substrate represents a promising alternative for investigating DNA methylation dynamics due to its unique properties.
Design and Synthesis of AffiZYME® Methylation Substrate
AffiZYME® Methylation substrate is designed based on the principles of affinity chromatography, utilizing a methyl-binding domain (MBD) to selectively capture methylated DNA fragments. The substrate consists of a solid support, such as magnetic beads or a microplate, functionalized with MBD proteins. These MBD proteins have high affinity and specificity for methylated CpG sites, allowing for the efficient enrichment of methylated DNA from complex mixtures. AffiZYME® Methylation substrate can be easily synthesized using recombinant DNA technology and protein purification techniques, ensuring reproducibility and scalability.
Biochemical Properties
AffiZYME® Methylation substrate exhibits several desirable biochemical properties for studying DNA methylation. It demonstrates high affinity and specificity for methylated DNA, enabling the selective enrichment of methylated regions from genomic DNA samples. The substrate is compatible with various downstream applications, including next-generation sequencing, PCR, and microarray analysis. Moreover, AffiZYME® Methylation substrate can effectively capture methylated DNA fragments from low-input samples, such as circulating cell-free DNA from blood plasma, facilitating non-invasive biomarker discovery and disease monitoring.
Applications in Epigenetic Research
AffiZYME® Methylation substrate has broad applications in epigenetic research, spanning basic science to clinical investigations. Researchers can utilize AffiZYME® Methylation substrate to profile DNA methylation patterns across the genome, identify differentially methylated regions associated with disease states, and elucidate the functional consequences of DNA methylation changes on gene expression. Furthermore, AffiZYME® Methylation substrate can be employed in high-throughput screening assays to identify small molecules that modulate DNA methylation, opening avenues for drug discovery and therapeutic development.
AffiZYME® Methylation substrate represents a versatile and reliable tool for studying DNA methylation dynamics in diverse biological contexts. Its high specificity, sensitivity, and ease of use make it well-suited for both basic research and translational applications. By leveraging the unique properties of AffiZYME® Methylation substrate, researchers can gain deeper insights into the role of DNA methylation in health and disease, ultimately paving the way for personalized approaches to diagnosis and treatment.
