Thermo Scientific™ MagnaBind™ Carboxyl Derivatized Beads

Description

Enable benchtop magnetic affinity purification with these ligand-coated (streptavidin, Protein A and G, GAM IgG, GAR IgG) magnetic particles and magnet separators.

Thermo Scientific™ MagnaBind™ Beads provide a convenient method for magnetic separation of antibodies, antigens, lectins, enzymes, nucleic acids and cells using affinity binding. To remove the MagnaBind Beads from the suspension, an external magnetic field is used.

MagnaBind Carboxyl Derivatized Beads are supplied as an aqueous suspension of magnetic iron oxide beads coated with carboxyl groups for covalent coupling of molecules using EDC, a zero-length crosslinker that is amine- and carboxyl-reactive. Additionally, carboxyl derivatized beads have been used to purify plasmid DNA from cells.
