Thermo Scientific™ Perline magnetiche e magneti MagnaBind™
Sfoglia Tutto Thermo Scientific ProdottiDescrizione
Thermo Scientific™ MagnaBind Magnetic Beads are available with streptavidin, Protein A, Protein G, GAM IgG, GAR IgG and other ligands for use in small-scale benchtop magnetic affinity protocols.
MagnaBind Beads are available pre-coated with Protein A, Protein G, streptavidin, anti-mouse or anti-rabbit antibodies. Also available are beads activated with either amine or carboxyl groups as targets for customized covalent immobilization other proteins or ligands.
Highlights:
- Available pre-coated with popular affinity ligands or derivatized for covalent attachment of proteins and other specific ligands
- Beads do not irreversibly aggregate because they have no magnetic memory; collect and disperse the beads multiple times if needed
- Most separations require a short five- to 10-minute benchtop procedure
Properties of underivatized MagnaBind Beads:
- Composition: silanized iron oxide
- Magnetization: 25 to 35 EMU/g
- Type of Magnetization: superparamagnetic (no magnetic memory)
- Surface Area: greater than 100m2/g
- Bead Size: 1 to 4μm diameter
- Settling Rate: 4% in 30 minutes
- Effective Density: 2.5g/mL
- Number of Beads: 1 x 108 beads per milliliter
- pH Stability: aqueous solution, above pH 4.0
- Concentration: 5mg/mL
Requires:
To remove MagnaBind Beads from suspension, an external magnetic field is used; see the ordering table for a selection of magnets.
Recommended for:
Cell sorting using either positive or negative selection; Protein purification or immunoassays using either direct or indirect methods; Immunoprecipiation
