Toxin detection method
View Patent ↗According to the present invention, an antibody against a Panton-Valentine leukocidin toxin contained in Staphylococcus aureus , a method and a kit for detecting the toxin with the use of the antibody, and a pharmaceutical composition containing an antibody against a Panton-Valentine leukocidin toxin for treating PVL infection caused by Staphylococcus aureus containing PVL are provided. Also, an antibody which is capable of binding to Panton-Valentine leukocidin F and has no cross-reactivity to LukD and/or HlgB and an antibody which is capable of binding to Panton-Valentine leukocidin S and has no cross-reactivity to at least one of LukE, HlgC, and HlgA are provided.
1. An isolated antibody capable of binding to Panton-Valentine leukocidin F (LukF-PV), wherein the isolated antibody does not specifically cross-react with at least one homologous protein of LukF-PV selected from the group consisting of LukD and HlgB.
2. An isolated antibody capable of binding to Panton-Valentine leukocidin F (LukF-PV), wherein the isolated antibody inhibits leukocytolytic toxin activity and does not specifically cross-react with at least one homologous protein of LukF-PV selected from the group consisting of LukD and HlgB.
3. A Panton-Valentine leukocidin detection kit comprising the isolated antibody according to claim 1 .
4. A Panton-Valentine leukocidin detection kit comprising the isolated antibody according to claim 2 .
