Product Overview
MNHS500-10 NHS Magnetic Beads are superparamagnetic microspheres with a nominal particle diameter of 500 nm and highly reactive NHS (N-hydroxysuccinimide) functional groups.
The NHS surface rapidly reacts with primary amino groups on antibodies, proteins, peptides and other biomolecules, enabling efficient covalent immobilization under mild conditions. The beads combine excellent magnetic responsiveness, high coupling efficiency and low nonspecific adsorption, making them suitable for a wide range of life science applications.
Supplied as a 5% aqueous suspension, MNHS500-10 provides excellent dispersion stability and reproducible performance for laboratory and industrial applications.

Product Advantages
MNHS500-10 NHS Magnetic Beads combine a 500 nm particle size with highly reactive NHS functional groups, providing a large specific surface area for efficient biomolecule coupling. The NHS groups react rapidly with primary amino groups, forming stable covalent bonds that improve immobilization efficiency while minimizing ligand loss.
The superparamagnetic iron oxide core enables fast magnetic separation without permanent magnetization, allowing convenient washing and repeated use in laboratory workflows.
