Application: Staphylococcal Enterotoxin B Peptide (144–153) corresponds to amino acid residues 144–153 of SEB, a highly conserved region among staphylococcal superantigens. This sequence has been shown to inhibit transcytosis of multiple staphylococcal enterotoxins, including SEA, SEE, and TSST-1, indicating its relevance in toxin transport mechanisms. SEB-derived peptides are widely used to study host–pathogen interactions, epithelial barrier function, superantigen uptake, and bacterial virulence pathways. This peptide supports research on toxin neutralization strategies, staphylococcal pathogenicity, immune activation, and molecular mechanisms underlying enterotoxin movement across epithelial barriers.
