Kas of SIGN-R1, hDC-SIGN, and hFcγRIIb for sialylated and asialylated IgG Fcs

Receptor 2,6 Fc Asialylated Fc
SIGN-R1 2.7 × 10−6 n.b.
hDC-SIGN 3.6 × 10−6 n.b.
hFcγRIIb 1.5 × 10−5 1.6 × 10−6

Ka values were determined by linear regression analysis of the equilibrium binding curves shown in Fig. 4B. n.b., no binding.
