Description

Staphylococcal Enterotoxin A (SEA) is a potent bacterial superantigen produced by certain strains of *Staphylococcus aureus*. This high-purity reference standard is critical for research, diagnostic development, and quality control in the life sciences sector. It is primarily utilized by pharmaceutical companies, contract research organizations (CROs), and academic institutions engaged in immunology, toxicology, and vaccine development.

Application

• Immunological Research: Used as a model superantigen to study T-cell activation, cytokine storms, and immune system modulation.
• Diagnostic Kit Development: Serves as a key antigen and positive control in the manufacturing of ELISA and lateral flow assays for detecting Staphylococcal food poisoning.
• Toxicology & Safety Testing: Employed in studies to understand the mechanisms of foodborne illness and to evaluate potential countermeasures or detoxification methods.
• Vaccine & Therapeutic Research: Acts as a target antigen in the development of vaccines and neutralizing antibodies against Staphylococcal infections.
• Quality Control & Standardization: Provides a certified reference material for calibrating analytical instruments and validating testing protocols in quality assurance laboratories.

Quality Control

Our Staphylococcal Enterotoxin A is produced and handled under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including purity assessment by HPLC and identity confirmation, to ensure it meets the exacting standards required for research and in-vitro diagnostic use. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as purity, endotoxin levels, and biological activity.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store desiccated at -20°C or below. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature before opening to prevent condensation.
