BeaverBeads Protein A Antibody Purification Kit

 1. Highly effective antibody binding capacity and ultra-low non-specific adsorption performance

• Protein A Matrix beads extract the purity of antibody IgG from 10-fold diluted human serum, which is substantially the same or even higher than the purity of IgG extracted directly from serum.

2. Time saving, simple and mild

• The picture below shows the BeaverBeads ™ bead application flow diagram

• Comparison with chromatographic - agarose gel purification

• 1. No centrifugation, magnetic separation can be used, and the use of the chromatograph-agarose gel purification system can greatly shorten the operating time
• 2. Avoid the error of the packing loss caused by repeated suction fluid
• 3. Avoid damage to active protein by mechanical shearing force in centrifugation

3. High product stability

• BeaverBeads ™ Protein A Matrix Magnetic Beads Stability Test. The magnetic beads were incubated at 37 ℃ for 8 weeks, and the antibody binding efficiency was not attenuated, which indicated that the beads had good stability.

4. Antibody elution system is closer to neutral

• This 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.

5. Very low protein A ligand off rate

• Protein A residues in antibody purification products for Beaver Beads ™ beads are lower than US FDA standards (20 ppm). And has been certified by the foreign well-known foreign products no significant difference.

6. 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.
