Silica Mag Beads OH (500 nm)

silica magnetic beads are specially designed for nucleic acid extraction and purification. The bead surface is composed of high-purity silica material enriched with silanol groups (hydroxyl groups) or carboxyl groups, which enable efficient and specific binding to nucleic acid molecules through hydrophobic interactions, hydrogen bonding, and electrostatic interactions under high-salt and low-pH conditions, while exhibiting minimal adsorption to impurities such as proteins. This allows rapid separation and purification of nucleic acids from complex biological samples.The product features a simple workflow and high operational safety, and is suitable for both manual operation and automated platforms, particularly for high-throughput nucleic acid extraction applications.
