title: Dioxin detection based on immunoassay using a polyclonal antibody against octa-chlorinated dibenzo-p-dioxin (OCDD).
abstract: An enzyme-linked immunosorbent assay (ELISA) using a polyclonal antibody against octa-chlorinated dibenzo-p-dioxin (OCDD) is presented. This method is based on a competitive reaction between OCDD and OCDD-HRP (horseradish peroxidase) conjugate against the antibody, whereby OCDD-HRP is detected colorimetrically at 450 nm. The detection limit of OCDD was 0.78 pg mL(-1). Optimizing the reaction conditions of the assay, cross reactivities of some dioxins against the antibody are discussed.
