Neutralization of Staphylococcal enterotoxin B by aptamer
12 Staphylococcal enterotoxin B (SEB) is a major virulence factor for 13 Staphylococcal toxic shock syndrome (TSS). SEB activates a large subset of the T 14 lymphocytic population, releasing pro-inflammatory cytokines. Blocking 15 SEB-initiated toxicity may be an effective strategy for treating TSS. Using a 16 systematic evolution of ligands by exponential enrichment (SELEX) process, we 17 iden...
متن کاملPurification of Type B Staphylococcal Enterotoxin.
Frea, James I. (University of Wisconsin, Madison), Elizabeth McCoy, and F. M. Strong. Purification of type B staphylococcal enterotoxin. J. Bacteriol. 86:1308-1313. 1963.-A procedure for the production and isolation of type B staphylococcal enterotoxin in yields up to 4 mg per liter of toxic culture is presented. Staphylococcus aureus S6 was grown in shake flask cultures at 37 C for 24 hr in a ...
متن کاملHydrogen ion equilibrai of staphylococcal enterotoxin B.
Potentiometric and spectrophotometric titrations of staphylococcal enterotoxin B have been carried out in 0.16 M KC1 at 25”. Potentiometric titration results indicate that the titration curves are essentially reversible between pH 1.50 and 11.0. All of the ionizable groups in enterotoxin B found from the titration curves are consistent with the amino acid composition which has been reported in ...
متن کاملGenetic Fingerprinting of Staphylococcal Enterotoxin B
Staphylococcal enterotoxin B (SEB), an exotoxin produced by staphylococcal aureus, is commonly associated with food poisoning and capable of triggering flu-like symptoms resembling those of endotoxins – such as lipopolysaccharide (LPS) released from gram-negative bacterial cell walls. By comparing the host response to these distinct toxins on a genetic level, a set of genes can be identified to...
متن کاملAnalysis of staphylococcal enterotoxin B by the polyacrylamide electrophoresis technique.
The electrophoretic mobility of enterotoxin B was investigated through the use of the disc electrophoresis technique. Ideal patterns were developed with a 7.5% acrylamide gel system (pH 4.3). The toxin can be separated and identified from other complex proteins such as serum or suspect samples of foods by this technique. The technique can be used as an assay method for the toxin as well as to e...
