Magnetic Beads

Magnetic Beads

To enable fast and efficient purification of antibody and epitope-tagged proteins, GenScript provides super paramagnetic MagBeads™. GenScript MagBeads are coated with recombinant protein ligands that enable highly specific affinity binding to antibodies and epitope-tagged proteins. The magnetic protein purification method allows for protein purification directly from cell lysates, thus eliminating the need for centrifugation steps and simplifying protein purification. The high binding capacity, specificity of binding, and the superfast magnetic response makes GenScript MagBeads ideal for applications requiring fast turnaround time and large number of samples.

Why choose magnetic beads?

The advantage of magnetic beads is that they aggregate without the stress of centrifugation, which can significantly increase the yield of delicately attached protein complexes. Additionally, magnetic beads are easy to separate from the supernatant by simply using a magnetic source close to your tube. This will allow the removal of unwanted supernatant without disturbing your protein pellet.
