title: Detection of staphylococcal enterotoxins A, B, C, D, and E in foods by radioimnunoassay, using staphyloccal cells containing protein A as immunoadsorbent.
abstract: A sensitive radioimmunoassay utilizing Staphylococcus aureus cells containing protein A as a coprecipitant was developed for the detection and quantitation of staphylococcal enterotoxins A, B, C, D, and E in a variety of foods. The enterotoxins were extracted from the foods by a simple and rapid procedure. The sensitivity of the assay is 1.0 ng or less of enterotoxin per g of food.
