In vivo LeTx neutralisation assay in F344 rats. a LeTx and the antibody were simultaneously injected via the tail vein. 0 μg, 0 μg PA21 + 30 μg LeTx; 5 μg, 5 μg PA21 + 30 μg LeTx; 10 μg, 10 μg PA21 + 30 μg LeTx. b Different concentrations of the antibody were injected, and 30 μg LeTx was injected 5 min later via the tail vein. c For each rat, 20 μg antibody was injected before (− 24 h, − 30 h) or after (5 min, 10 min) LeTx
