Evaluation of Handheld Assays for the Detection of Ricin and Staphylococcal Enterotoxin B in Disinfected Waters

<table>SDS-PAGE analysis of SEB treated with chlorine. Lane 1: molecular mass standards (in kilodaltons); lane 2: untreated control SEB after 1 min; lane 3: chlorine-treated SEB after 1 min; lane 4: untreated control SEB after 1 hour; lane 5: chlorine-treated SEB after 1 hour; lane 6: untreated control SEB after 24 hours; lane 7: chlorine-treated SEB after 24 hours. Arrows indicate 31 kDa molecular weight marker (top arrow) and 28 kDa SEB (bottom arrow).</table>
