Highly sensitive sandwich immunoassay and immunochromatographic test for the detection of Clostridial epsilon toxin in complex matrices

Abstract: Epsilon toxin is one of the four major toxins of Clostridium perfringens. It is the third most potent clostridial toxin after botulinum and tetanus toxins and is thus considered as a potential biological weapon classified as category B by the Centers for Disease Control and Prevention (CDC). In the case of a bioterrorist attack, there will be a need for a rapid, sensitive and specific detection method to monitor food and water contamination by this toxin, and for a simple human diagnostic test. We have produce… Show more

“…[73] Immunoassay is am ethod of binding an antigen to an antibodyf or the recognition of ap athogen. [74][75][76] As showni nF igure 3, captured antibodies were immobilized on microplates following incubation and washing with blocking buffer to preventthe protein from reaching nonspecific sites. Different concentrations of the HIV p24 antigen were incorporated ontoc aptured antibody to which the biotinylated detector bound for interaction with the streptavidinconjugated AgNPs (FSN-SA) required for fluorescenced etection.…”

“…C. perfringens nie produkuje 13 z 20 podstawowych aminokwasów, a zapotrzebowanie zaspokaja przez rozkład tkanek gospodarza z udziałem produkowanych toksyn i enzymów (1). W gramie treści jelitowej zdrowego człowieka spotyka się 10 5 C. perfringens, a u osób z objawami zatrucia pokarmowego stwierdzano 10 7 jtk/g (18). Żywnością najczęściej zanieczyszczoną jest mięso i jego przetwory, rzadziej ryby, warzywa, produkty mleczne, żywność suszona czy przyprawy (4,59,70).…”

“…Jak dotąd opisano 20 toksyn C. perfringens (tab. 1), co sprawia, że jest on jednym z największych producentów toksyn wśród znanych mikroorganizmów (18,57). Toksyny te można podzielić na cztery kategorie, tj.…”
