Description

Enterotoxin D, Staphylococcal is a potent bacterial exotoxin produced by certain strains of *Staphylococcus aureus*. This high-purity reference standard is critical for research, diagnostic development, and quality control in the food safety and pharmaceutical industries. It is primarily utilized by microbiologists, immunologists, and analytical scientists for the study of staphylococcal food poisoning, toxin detection method validation, and immunological assay development.

Application

• Research & Diagnostic Development: Essential for developing and validating sensitive immunoassays (ELISA, Lateral Flow) and PCR-based methods for the detection of Staphylococcal Enterotoxin D (SED) in food and clinical samples.
• Food Safety Testing: Serves as a critical reference standard and positive control in laboratories monitoring food products for staphylococcal enterotoxin contamination to ensure public health safety.
• Toxicological Studies: Used in academic and industrial research to investigate the mechanisms of action, superantigen activity, and emetic properties of SED.
• Vaccine & Antitoxin Research: Acts as a key antigen in the research and development of potential vaccines and therapeutic antitoxins against staphylococcal infections.
• Quality Control & Method Validation: Employed as a certified reference material to calibrate equipment, qualify reagents, and validate analytical procedures in compliance with ISO and other regulatory guidelines.
• Antibody Production & Characterization: Used as an immunogen to generate specific polyclonal or monoclonal antibodies for diagnostic and research applications.
