General description

Staphylococcus aureus is a Gram positive bacterium, that cause diseases in human population including food poisoning and toxic shock syndrome.1 S. aureus express several secreted virulence factors, such as various enzymes, cytotoxins, exotoxins, and exfoliative toxins.1 Exotoxins include more than 20 serologically classified staphylococcal enterotoxins (SEs), the best characterize are the SEs A, B through V and toxic shock syndrome toxin-1 (TSST-1), these enterotoxins are similar in activity, sequence, structure and molecular weight (~25-30 kDa).1

Specificity

Anti- Staphylococcal Enterotoxin B- peroxidase antibody specifically recognizes Staphylococcal Enterotoxin B (SEB) and has no cross reactivity with Staphylococcal Enterotoxin A (SEA), Cholera Toxin or Pseudomonas Exotoxin A.

Immunogen

purified Enterotoxin B from Staphylococcus aureus

Application

The antibody may be used in various immunochemical techniques including ELISA.

Biochem/physiol Actions

SEA and SEB are known as superantigens due to their ability to bind class II MHC molecules on antigen presenting cells and stimulate extensive T-cells activation followed by massive cytokine release leading to an acute toxic shock.1-4

SE proteins have a significant resistance to heat and acid, it is also resistant to gastrointestinal proteases including pepsin, trypsin, rennin and papain. Thus, killing the S. aureus bacteria may not be sufficient to eliminate these superantigens risk from causing food poisoning.

Physical form

Supplied as a lyophilized powder.

Storage and Stability

Store the lyophilized product at 2–8 °C. For extended storage after reconstitution, keep at –20 °C in working aliquots. Avoid repeated freeze-thaw cycles. For continuous use after reconstitution, keep at 2–8 °C for up to 1 month. Solutions at working dilution should be discarded if not used within 12 hours.
