Absolute Mag™ Tosyl Magnetic Particles, 4.5 µm(WHM-L030)


Absolute Mag™ Tosyl Magnetic Particles, 4.5 µm (# WHM-L030) contain surface tosyl groups. The beads covalently bind primary amino and sulfhydryl groups in antibodies to position them in the optimal orientation for cell-surface protein binding. Low background and covalent binding of the antibodies make these particles an excellent choice for cell separation applications when a downstream release from the beads is not required.

Application Notes
Absolute Mag™ Tosyl Magnetic Particles, 4.5 µm (# WHM-L030) coupled with antibodies or other ligands provide a versatile tool for isolation of both cells and non-cell targets (e.g. proteins and other biomolecules). Their size makes them particularly suitable for stimulation and expansion of e.g. T cells. Cells can be directly isolated from any sample such as whole blood, bone marrow, mononuclear cell suspensions (MNC) or tissue digests. The particles react covalently with proteins (e.g. antibodies) or other ligands containing primary amino or sulphydryl groups.
