Immunofluorescent Detection of Staphylococcal Enterotoxin B II. Detection in Foods

摘要

SUMMARYSpecific staphylococcal enterotoxinBanti‐serum conjugated with fluorescein isothiocyanate was used successfully for detecting toxin in food smears or food extracts in about 4–5 hr. The fluorescent antibody technique detected minute amounts of enterotoxin—much less than 1 or 0.05 μg/ml, which are the sensitivity limits of single or double gel diffusion tube tests—‐without involving any extraction
