Neutralization of recombinant leukocidins by ASN-1 and ASN-2. A: Neutralization of recombinant HlgAB (10 nM), HlgCB (7.5 nM), LukED (10 nM) and LukSF-PV (5 nM) by ASN-1. B: Neutralization of LukGH (1 nM, TCH1516 LukGH) by ASN-2. C: left panel: Effect of individual toxins as in A, except for LukGH (1.875 nM each of the four LukGH variants expressed based on the MRSA252, MSHR1132, H19 and TCH1516 sequences) and a mixture thereof on PMN viability; right panel: Neutralization of a mixture of recombinant toxins by ASN-1, ASN-2 or ASN100 (1:1 mixture of ASN-1 and ASN-2). Antibody concentrations shown refer to individual mAbs. PMN viability was determined by luminescent quantification of cellular ATP levels. Data are derived from at least two independent experiments and shown as mean +/− SEM.
