Description: : Purified, His-tagged Staphylococcus aureus PantonValentine Leukocidin (PVL) S subunit (LukS-PV). The theoretical molecular weight of the protein is 33,713 Daltons including the His-tag.
Size: 100 ug of protein is supplied in PBS + 15% Glycerol at a concentration of 1 mg/mL. Protein demonstrates a molecular weight of approximately 30 kDa.
Relevance: This protein may be used in functional PVL toxicity assays in combination with LukF-PV, or as a control protein in ELISA assays or Western blotting when detecting LukS in PVL (+) strains of S. aureus.
Recommended Dilutions:
ELISA: Assay-dependent dilution; internal QC demonstrates detection down to 1 ng/mL of LukS-PV protein when detected with mouse anti-LukS monoclonal antibody (cat # 0221-001) as capture and rabbit anti-LukS polyclonal antibody (cat# 04-0009) as a secondary followed by anti-rabbit horseradish peroxidase conjugate and substrate.
WB: Assay-dependent dilution; internal QC demonstrates detection of 1 ng of LukS-PV protein when detected with anti-PVL LukS polyclonal antibody (cat# 04-0009) in Western blotting.
PVL Cytotoxicity assay: Cytotoxicity can be detected in human neutrophils when used in combination with LukF-PV in a concentration range of 1-100 nM.
Storage: 2-3 weeks at -20°C, -80°C long term.
