Activity : 1. Measured by its binding ability in a functional ELISA. Immobilized human sCD32b-His (CHO) (Cat:10259-H08C) at 10 £gg/ml (100 £gl/well) can bind biotinylated human IgG1, The EC50 of biotinylated human IgG1 is 0.18-0.42 £gg/ml.
2. Using the Octet RED System, the affinity constant (Kd) of CD32B / Fcgr2b Protein, Human, Recombinant (His Tag) (Cat. 10259-H08C) bound to Conbercept was 0.3 nM.
