Epigenetic regulation lies at the core of cellular identity, developmental programs, and transcriptional control. While DNA sequence provides the blueprint, it is the chromatin landscape—the dynamic organization of DNA and associated proteins—that determines which genes are accessible, active, or silenced. As a result, technologies that accurately map protein–DNA interactions are essential tools in modern genomics…

In modern molecular biology laboratories, sample purification and size selection are as critical as enzymatic reactions themselves. Whether preparing DNA libraries for next-generation sequencing (NGS), purifying PCR products, or removing contaminants from enzymatic reactions, clean-up beads have become an essential tool across genomics, transcriptomics, and molecular diagnostics. Magnetic clean-up beads, most commonly based on solid-phase…
