Enterotoxin type E Protein, S. aureus (HEK293, His, Myc)
Based on 1 Customer Validation
ENTE Proteinas are staphylococcal enterotoxins that activate the host immune system by binding to major histocompatibility complex class II and T-cell receptor (TCR) molecules. This interaction forms a ternary complex that activates T lymphocytes and induces the systemic release of proinflammatory cytokines. Enterotoxin type E Protein, S. aureus (HEK293, His, Myc) is the recombinant Staphylococcus aureus-derived ENTE protein, expressed by HEK293 , with N-6*His, N-Myc labeled tag.
- Species: Staphylococcus aureus
- Source: HEK293
-
Storage:Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Description
ENTE Proteinas are staphylococcal enterotoxins that activate the host immune system by binding to major histocompatibility complex class II and T-cell receptor (TCR) molecules. This interaction forms a ternary complex that activates T lymphocytes and induces the systemic release of proinflammatory cytokines. Enterotoxin type E Protein, S. aureus (HEK293, His, Myc) is the recombinant Staphylococcus aureus-derived ENTE protein, expressed by HEK293 , with N-6*His, N-Myc labeled tag.
Background
ENTE, a staphylococcal enterotoxin, plays a pivotal role in activating the host immune system by binding as unprocessed molecules to major histocompatibility complex class II and T-cell receptor (TCR) molecules. This interaction results in the formation of a ternary complex, which, in turn, activates a significant number of T-lymphocytes, triggering a systemic release of pro-inflammatory cytokines. Beyond its immunomodulatory functions, ENTE is implicated in the development of staphylococcal food poisoning syndrome, a condition characterized by symptoms such as intoxication, fever, and gastrointestinal distress. These activities highlight the impact of ENTE on both immune response pathways and pathological outcomes.
