The dense beads provide reliable collection of the bound proteins/antibodies.
GE Healthcare has launched His Mag Sepharose Ni, Protein A Mag Sepharose Xtra,
and Protein G Mag Sepharose Xtra magnetic beads. The new magnetic beads
provide high binding capacity, for fast separation and high quality results.
The highly visible, dense beads provide superior purity and yield, with easy
parallel screening and high repeatability. Handling is simplified as rapid
capture is facilitated by magnetic devices, and visibility ensures reliable
collection of the bound proteins/antibodies. The process is easily scalable,
enabling simple capture of target protein or antibody from low microliter to
His Mag Sepharose Ni beads are designed for purification/screening of
histidine-tagged proteins from cell lysates and supernatants. Protein A Mag
Sepharose Xtra and Protein G Mag Sepharose Xtra beads are designed for
purification/screening of monoclonal and polyclonal antibodies from cell
culture supernatant and biological fluid.
The binding capacity is >27 mg human IgG/ ml medium on Protein A Mag Sepharose
Xtra and Protein G Mag Sepharose Xtra and >50 mg (protein dependent)
histidine-tagged protein/ml medium on His Mag Sepharose Ni.
In addition to the Mag Sepharose beads, MagRack 6 is also available, allowing
scientists to prepare up to six samples captured in 1.5 ml microcentrifuge
tubes. When the tubes are placed in the rack, the magnetic beads are
attracted to the magnet within a few seconds and enable the supernatant to
be easily removed while the magnetic beads are retained in the tube.
