Product Advantages
MTOS10UM-10 combines excellent magnetic responsiveness with a larger particle size for convenient handling and fast separation. The 10 μm particle size offers a high active surface for biomolecule immobilization while allowing rapid magnetic collection.
The tosyl-functionalized surface reacts with suitable amino or sulfhydryl groups to create stable covalent bonds, ensuring reliable coupling efficiency and minimizing ligand loss during repeated washing and separation procedures.
The superparamagnetic iron oxide core enables efficient magnetic separation while preventing permanent aggregation after removal of the magnetic field.
Storage and Handling
