Used as a biochemical reagent in research laboratories for studying methylation processes in DNA, proteins, and other biomolecules. It serves as a methyl group donor in enzymatic reactions, making it valuable in epigenetics and molecular biology studies. Commonly applied in in vitro assays involving methyltransferases to investigate gene regulation, chromatin modification, and metabolic pathways. Also utilized in cell culture systems to modulate methylation status and assess downstream effects on gene expression and cellular function. Stable form suitable for long-term storage in experimental settings requiring consistent reagent performance.
