Analysis of Staphylococcus enterotoxin B using differential isotopic tags and liquid chromatography quadrupole ion trap mass spectrometry

ABSTRACT Staphylococcus aureus produces enterotoxins, which are causative agents of foodborne intoxications. Enterotoxins are single‐chain polypeptides and have a molecular weight of about 26–28 kDa. The consumption of food contaminated with Staphylococcus aureus enterotoxins results in the onset of...
