Magnetic silica beads with Protein G covalently bound to the surface. Bead size is 1um.
Catalog #M2106-04
The recombinant Protein G (~26kD) on the surface of our beads contain only IgG binding sites. The albumin, cell wall and cell membrane binding domains, present on the wild-type Protein G, have been removed to optimize binding properties. The advantage of Protein G beads, compared to Streptavidin beads, is that the antibody does not need to be biotinylated and the binding is reversible. These beads are ideal for protein isolation and proteomic applications. More importantly, the magnetic properties of the beads allow quick and easy washing steps for protein isolation.
ApplicationsSuitable for use in IgG capture, Capture/Immunoprecipitation, IgG elution and target elution.
Other applications have not been tested.
Storage and StabilityMay be stored at 4°C. For long-term storage, store at 4°C. Do not freeze! Store beads in well closed vial and in upright position to prevent drying of the beads since this makes them more difficult to resuspend and may decrease their activity. Vortex bead suspension well before use. Beads are stable for 6 months.
Use of MagDetect™ Magnetic SeparatorsMagnetic separators are required to work with magnetic beads. MagDetect™ Separators work with all MagDetect™ products as well as all competitive magnetic beads on the market.
M2106-80, Magnetic Bead Separator 12+12 for MagDetect™ beads in 12x1.5ml and 12x 2ml tubes. M2106-81, Magnetic Bead Separator 96 well for MagDetect™ beads in microplate format. M2106-82, Magnetic Bead Separator, PCR Strip Adapter, MagDetect™ (use with M2106-81). PCR strip Adapter is placed on the 96 well Separator and is suitable for users with smaller sample throughput, preferring use of PCR tube strips over PCR plates.
