BeaverBeads™ Magrose ProteinG Antibody Purification

BeaverBeads™ Protein A, Protein G are superparamagnetic beads covalently coated with recombinant Protein A or Protein G that contains Fc binding domains for the purification of monoclonal or polyclonal antibodies from cell lysate, blood plasma, ascites and tissue culture supernatant, and for antibody immobilization studies. The one-step solution can reduce the antibody absorption process to 10 minutes and purification process to 30 minutes, yielding antibody with >90% purity.

▪ Highly effective antibody binding capacity and ultra-low non-specific adsorption performance
▪ Time saving, simple and mildam
No centrifugation, magnetic separation can be used, and the use of the chromatograph-agarose gel purification system can greatly shorten the operating time
Avoid the error of the packing loss caused by repeated suction fluid
Avoid damage to active protein by mechanical shearing force in centrifugation
▪ High product stability
▪ Antibody elution system is closer to neutral
The product uses an optimized elution buffer to elute antibodies at pH 4.5, greatly reducing the risk of acid-sensitive antibodies being damaged in low pH elution environments.
▪ Very low protein A ligand off rate
▪ Reusable
BeaverBeads™ antibody purified beads can be reused and regenerated, and maintain high antibody binding efficiency. After 15 uninterrupted purification operations, 75% of the lgG binding capacity was maintained, and the antibody binding capacity was restored to the original 90% after regeneration treatment.
