Product Overview
MNHS3UM-10 NHS Magnetic Beads are superparamagnetic microspheres with a nominal particle diameter of 3 μm 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 reaction conditions. These beads provide excellent magnetic responsiveness, high coupling efficiency and low nonspecific adsorption, making them suitable for immunoassays, affinity purification and biotechnology applications.
Supplied as a 5% aqueous suspension, MNHS3UM-10 delivers excellent dispersion stability and reproducible performance for research, diagnostic and industrial laboratories.

Product Advantages
MNHS3UM-10 NHS Magnetic Beads combine a 3 μm particle size with highly reactive NHS functional groups, offering an excellent balance between magnetic separation efficiency and active surface area for biomolecule immobilization. The NHS groups rapidly react with primary amino groups to form stable covalent bonds, resulting in high coupling efficiency and excellent experimental reproducibility.
The superparamagnetic iron oxide core enables fast magnetic separation without residual magnetization, making repeated washing and resuspension simple and efficient.
