SPE-B: Native
Native Streptococcal Pyrogenic Exotoxin (SPE) Type B
When your research requires investigation of dual-function superantigen and cysteine protease mechanisms in streptococcal pathogenesis, this native SPE-B delivers the unique bifunctional activity you need. Our purification process preserves SPE-B’s characteristic superantigenic properties and cysteine protease activity, ensuring your experimental results reflect true streptococcal virulence mechanisms for invasive disease and toxic shock syndrome research.
Key Advantages
- Dual superantigen and cysteine protease functionality for comprehensive virulence studies
- Preserved MHC class II binding and TCR activation for superantigen research
- Active proteolytic activity for tissue damage and invasion mechanism studies
- Essential for streptococcal toxic shock syndrome and invasive disease research
This research-grade preparation maintains trace co-purifying substances detectable by sensitive analytical methods, providing transparency for your experimental design. These reagents are intended for laboratory and research purposes only. They are not intended for human or veterinary drug use.
