Endotoxin neutralization by a gal-III specific mAb in vitro. Endotoxin signaling through TLR4 was measured in a cell-based colorimetric assay in the presence of mAb A1102. (A) using purified LPS extracted from 3 isolates expressing gal-III (KP150, KP151, PCM-27). A1102 mAb (red curves), isotype matched control mAb (black curves), or polymyxin B (PMB, blue curves) were used at the indicated concentrations. (B) using shed LPS in supernatants of mid-log phase cultures of ST258 isolates as well as strain PCM-27. (C) Neutralizing potency of A1102 compared with its fragments as well as an aglycosylated (N297Q) version.
