一般描述

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

特异性

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.

免疫原

purified Enterotoxin B from Staphylococcus aureus

应用

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

生化/生理作用

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.

外形

Supplied as a lyophilized powder.
