GenScript’s AmMag Block enables protein and antibody purification from cultures up to 1 L in volume using the AmMag SA. Magnetic beads are directly incubated in cultures or lysates to bind the target proteins or antibodies. Once binding is complete, the AmMag Block is used to collect the beads at the bottom of the culture vessel, and the supernatant is discarded. The magnetic beads thus collected are re-suspended in a smaller volume and transferred into 50 ml tubes, to be washed and eluted automatically using the AmMag SA purification system, or manually using the AmMag MR magnetic racks.
