Description

Staphylolysin CAS NO 66554-76-5 is a purified bacterial exotoxin, specifically a hemolysin produced by *Staphylococcus aureus*. This compound is of significant value for research and diagnostic applications due to its specific lytic activity against red blood cells and other target membranes. It is primarily required by biotechnology firms, academic research institutions, and diagnostic kit manufacturers for use in microbiological studies, virulence factor analysis, and as a critical reagent in hemolysis assays.

Application

• Microbiological Research: Used as a standard toxin to study the pathogenesis and virulence mechanisms of *Staphylococcus aureus*.
• Diagnostic Reagent: Serves as a key component in diagnostic kits for identifying and characterizing staphylococcal strains based on hemolytic patterns.
• Cell Biology Studies: Employed to investigate pore-forming toxin mechanisms and host cell membrane interactions.
• Vaccine & Antitoxin Development: Acts as a critical antigen in the research and development of vaccines and therapeutic antitoxins.
• Quality Control in Biotechnology: Used as a reference standard in the quality control of related biological products and assays.
• Educational & Training Material: Supplied to educational institutions for practical laboratory training in medical microbiology.
