Anti-Staphylococcus aureus Antibody

This polyclonal primary antibody is raised in rabbit and affinity-purified as an Ig fraction, specifically targeting whole-cell Staphylococcus aureus. Distributed at 500 µL per vial as an unconjugated preparation, the reagent is compatible with downstream labeling workflows that demand free immunoglobulin — HRP, biotin, or fluorophore conjugation can be carried out by the end user. Practical applications include ELISA plate-based detection of bacterial antigen, immunofluorescence assay (IFA) imaging of fixed bacterial smears or clinical specimens, and Western blot confirmation of S. aureus protein lysates. Researchers studying nosocomial infection, food microbiology contamination screening, veterinary pathogen identification, or biofilm-expression work rely on such polyclonal reagents for the breadth of epitope coverage that helps recognize multiple protein and surface-antigen targets across diverse S. aureus strains, including methicillin-resistant lineages. The reagent is supplied for laboratory investigation of bacterial pathogenesis, host-pathogen interaction studies, and the development of in vitro research immunoassays rather than for therapeutic use. Short-term refrigerated handling preserves activity, while longer-term storage at -20 °C with single-use aliquots avoids repeated freeze-thaw cycles; with each vial providing 500 µL, the format supports multiple assay runs from one purchase.
