Product Overview
MTOS5UM-10 Tosyl Magnetic Beads are superparamagnetic microspheres with a nominal particle diameter of 5 μm and reactive tosyl-functionalized surfaces.
The tosyl groups enable covalent coupling with primary amino or sulfhydryl groups present in antibodies, proteins, enzymes and other biomolecules. This provides stable biomolecule immobilization for affinity purification, immunoassays, protein separation and numerous life science applications.
Supplied as a 5% aqueous suspension, the beads provide excellent magnetic responsiveness, high suspension stability and reliable batch-to-batch consistency.

Product Advantages
MTOS5UM-10 combines rapid magnetic separation with a larger bead size that is easy to handle during laboratory workflows. The 5 μm particle size provides a large active surface for biomolecule immobilization while maintaining excellent magnetic recovery efficiency.
The tosyl-functionalized surface forms stable covalent bonds with proteins and antibodies containing suitable amino or sulfhydryl groups, ensuring high coupling efficiency and excellent stability throughout repeated washing and separation procedures.
The superparamagnetic iron oxide core allows fast magnetic collection while preventing permanent aggregation once the magnetic field is removed.
Storage and Handling
Store at 2–8°C.
Do not freeze.
Keep the container tightly sealed.
Gently invert or vortex before use.
Ensure the beads are fully resuspended before sampling.
Avoid prolonged exposure to strong magnetic fields during storage.
Use clean laboratory equipment to avoid contamination.
