Magrose Protein A Magbeads for Protein Purification 30-150 μm, 10% (v/v)
1, Description:
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. This product is micron magnetic beads, skilled operation can complete the antibody adsorption process within 15 min, and complete the process of antibody purification within 30 min. It can be used for antibody fixation and other related studies. By referring the attached Table 1 users can select the categories of magnetic beads according to the source and subtype of the target antibody, and compare the affinity of Magrose Protein A and Magrose Protein G beads with different antibodies.

4, FAQ:
Q1: How to avoid possible aggregation of magnetic beads during storage or use?
A1: 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.
Q2: How to solve magnetic bead adhere to tube wall?
A2: It is recommended to use the consumables with low adsorption rate. In addition, adding 0.01%~0.1%(v/v) nonionic detergent (such as NP-40, Tween-20 or Triton X-100) to the buffer solution can effectively reduce the adhesion of beads on tube wall.
