Application of a rapid automated immunosensor for the detection of Staphylococcus aureus enterotoxin B in cream

An automated immunosensor has been applied to the detection of Staphylococcus aureus enterotoxin B in cream. It was capable of detecting the toxin down to a level of 5 ng/g in approximately 10 min. This paper describes the immunosensor method used and how it compares with conventional ELISA (enzyme linked immunosorbent assay) methods.
