11.SDS-PAGE

Determined by SDS-PAGE, the purity of the protein is greater than 90%.

12.ELISA

When Recombinant Human CD89/His Protein is immobilized at 2μg/mL (100 μL/well), the concentration of Anti-Human CD89(clone:8F3) that produces 50% of the optimal binding response is approximately 30 ng/ml.
