The suitability of competitive enzyme-linked immunosorbent assays (ELISAs) with chemiluminescent detection based immobilized antigen (indirect assay) for rapid an accurate determination of chlorpyrifos in different food matrices was tested. The limit of detection (LOD) value were between 1-1.75 ng ml-1, the standard curve midpoint (IC50) was 3.5 ng ml-1, and assay duration was 1.5 h.

Abstract
The suitability of competitive enzyme-linked immunosorbent assays (ELISAs) with chemiluminescent detection based immobilized antigen (indirect assay) for rapid an accurate determination of chlorpyrifos in different food matrices was tested. The limit of detection (LOD) value were between 1-1.75 ng ml-1, the standard curve midpoint (IC50) was 3.5 ng ml-1, and assay duration was 1.5 h. Assay application to the analysis of honeybees extract resulted in chlorpyrifos recoveries varying between 62 and 83 % in 5-15 ng ml-1 herbicide concentration range.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
