Development of an enzyme-linked immunosorbent assay for carbaryl

Abstract: Seven rabbit antisera were obtained by immunization with either N-(l-naphthylacetyl)-6-aminohexanoic acid (3) or l-(l-naphthyl)-3-(5-carboxypentyl)urea (8) conjugated to keyhole limpet hemocyanin (KLH). From these sera Ab2114 (against 8KLH) was used for the optimization of an enzyme-linked immunosorbent assay (ELISA) for the determination of the insecticide carbaryl. An I50 of 2-5 ng/mL and a detection limit of 0.2 ng/mL were obtained using N-(2-naphthoyl)8-aminohexanoic acid (5) coupled to conalbumin as a coa… Show more

“…Since organic solvents are commonly used in the sample preparation for nonpolar pesticides, it is desirable to assess the effects of organic cosolvents on ELISA characteristics. Since several workers reached the same conclusion that methanol causes the least negative effect of the solvents tested, [18][19][20] methanol was chosen as a cosolvent. Table 1 shows the effect of methanol concentration on ELISA performance.…”

“…Con respecto al carbaryl, el primer IA descrito es de tipo ELISA y está basado en anticuerpos policlonales (Marco et al, 1993). El mismo grupo desarrolló un ELISA para la determinación de 1-naftol, el principal metabolito del carbaryl (Krämer et al, 1994).…”

“…Se han descrito también métodos basados en la técnica ELISA e inmunosensores en flujo para la determinación de carbaril, utilizando tanto anticuerpos policlonales (46,165) como monoclonales (166)(167)(168)(169). Todos estos formatos de ensayo se caracterizan por su alta sensibilidad (I 50 < 0,1 µg/l) y baja reactividad cruzada con otros productos fitosanitarios de la misma familia.…”
