Magnetic Silica Beads for Immobilization

MagSi magnetic silica beads are surface activated magnetic particles for covalent immobilization of proteins, peptides, nucleic acids or other molecules of interest. Different surface modifications and bead sizes allow for the selection of the optimal product for the application and molecule to be coupled. The MagSi platform has a broad range of functionalization possibilities such as COOH, NH₂, SH, CHO, tosyl, hydrazide and epoxy. MagSi beads are available with 600nm, 1µm or 3µm mean diameters.
