Product Description

Protein A Antibody Purification Kit for Protein Purification 2μm, 30 mg / mL
1, Description:

BeaverBeadsTM Protein A(or Protein G) antibody purification beads are NHS activated superparamagnetic beads covalent binding Protein A (or Protein G). Compared with the similar products in the international market, the product has higher antibody binding capacity and lower protein non-specific adsorption rate, and the elution conditions are more homogeneous. The antibody can be separated from the serum sample by one-step purification, and the purity of the antibody is more than 90%.

3, Feature:


  • 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

4, FAQ:

Q1: How to improve the binding efficiency of antibody with magnetic beads?
A1: The binding efficiency of antibody with magnetic beads is related to the origin of the antibody and its subtype, refer to the type of antibody and the affinity efficiency of Protein A ligand antibody. (See attached table 1 ). If the antibody subtype has low affinity with Protein A , users can increase incubation time between antibody and beads (30~120 min), increase pH value (8~9) of the combination buffer and decrease ionic strength (25~100 mM NaCl) to increase affinity efficiency, or select the target antibodies with higher affinity ligands (such as Protein G or Protein A/G).
Q2: How to avoid possible aggregation of magnetic beads during storage or use?
A2: Beads should be stored at 2~8℃, and avoid for irreversible aggregation due to contamination or drying. Magnetic beads aggregation at low pH elution buffer is a normal phenomenon, and it does not affect the normal use of magnetic beads. In Binding/Washing buffer and Elution buffer adding with the final concentration of 0.1% (v/v) nonionic detergent (such as NP-40, Tween-20 or Triton X-100) can effectively prevent the beads
aggregation. The magnetic beads in low pH elution can be washed to neutral with Binding/Washing buffer and Elution buffer, and process with 2 min ultrasonic water bath. It can restore the magnetic beads to homogeneity,
and the above treatments had no effect on the antibody binding efficiency with magnetic beads.
