Product Overview
MNHS20UM-10 NHS Magnetic Beads are superparamagnetic microspheres with a nominal particle diameter of 20 μm and highly reactive NHS (N-hydroxysuccinimide) functional groups.
The NHS-functionalized surface rapidly reacts with primary amino groups on antibodies, proteins, peptides and other biomolecules, enabling stable covalent immobilization under mild reaction conditions. The beads provide excellent magnetic responsiveness, high coupling efficiency and low nonspecific adsorption, making them suitable for immunoassays, affinity purification, protein immobilization and biotechnology research.
Supplied as a 5% aqueous suspension, MNHS20UM-10 offers excellent dispersion stability, rapid magnetic separation and consistent batch-to-batch performance.

Product Advantages
MNHS20UM-10 NHS Magnetic Beads combine a 20 μm particle size with highly reactive NHS functional groups, providing rapid magnetic separation and a large active surface for efficient biomolecule immobilization. The NHS groups react quickly with primary amino groups to form stable covalent bonds, ensuring high coupling efficiency and excellent experimental reproducibility.
The superparamagnetic iron oxide core allows rapid magnetic collection without permanent magnetization, making repeated washing, separation and resuspension efficient for both laboratory research and large-scale bioprocessing applications.
