Abnova's magnetic beads conjugation services offer three particle sizes to meet customer’s objectives. We help you conjugate magnetic beads with antibodies based on your selection. The high binding capacity of our magnetic beads facilitates the antibody conjugation and allows researchers to achieve highly concentrated antibodies for further applications.

Since every antibody has its own unique characteristics, conjugation needs to be optimized. 100 μg of total antibody of interest will be tested and analyzed prior to mass labeling. We will complete the conjugation within 2 weeks from the time we receive the antibody samples.

Special Notes

  • The antibody of interest should not contain albumin, gelatin, or other amine-containing stabilizers and should be stored in PBS buffer. Purification of antibody from ascites fluid, serum, cell culture medium or removal of stabilizer proteins prior to conjugation will result in additional cost to the customer.
  • Minimum quantity of antibody conjugation is 100 μg. Minimum concentration is 1 mg/mL.
