Flavivirus studies:
YFV-17D was grown on Vero cells, and for antigenicity studies purified virus was exposed to dilutions of H2O2 (Fisher Scientific), formaldehyde (Fisher Scientific) or BPL (Sigma-Aldrich) at 2024 C, diluted to 1 g ml1 and used to coat ELISA plates. YFV-immune mice were infected intraperitoneally with 1 106 PFU of YFV-17D, and immune serum was obtained at 220 d after infection. WNV-NY99 was grown on Vero cells and purified by ultracentrifugation using 36% (w/v) sucrose cushions in PBS (pH 7.4) at 110,000g for 2.5 h at 4 C. Pellets were resuspended in PBS, pH 7.4 and inactivated with 3% H2O2 for 2 h at 2024 C, with inactivation confirmed by plaque assay on Vero cells before final formulation and immunization. Mice were immunized subcutaneously with 10-g doses of H2O2-WNV formulated with 50 g of aluminum hydroxide (alum, Sigma-Aldrich) and 5 g of monophosphoryl lipid A (MPL, List Biological Laboratories, Campbell, CA) …

Results – Sp-D Binding to SIRP Is Calcium-dependent, Carbohydrate-specific, and Inhibited by LPS :
… Sp-D is also known to bind with high affinity to rough LPS, the major component of Gram-negative cell walls (19). Therefore, we assessed whether Sp-D binding to SIRP was affected by LPS from S. minnesota Re mutant that expresses a truncated rough LPS known to be a strong ligand for Sp-D (37). The Re mutant expresses the shortest form of LPS among different S. minnesota strains containing only lipid A and 3-deoxy-d-manno-octulosonic acid (38). As shown in Fig. 3C, increasing concentrations of LPS significantly decreased Sp-D binding to SIRP. We observed 50% inhibition of Sp-D binding to SIRP at a concentration of 40 g/ml LPS, which is consistent with previous reports (39).
