title: An enhanced chemiluminescence enzyme immunoassay for serum oestradiol.
abstract: Oestradiol in serum was determined with a simple enhanced chemiluminescent enzyme immunoassay. The assay is based on oestradiol labelled with horseradish peroxidase and the IgG fraction of an oestradiol antiserum coated on a black polystyrene microtitre plate. The enzyme activity of bound label was determined using a p-hydroxycinnamic acid-enhanced chemiluminescent reaction. The assay was sensitive (1.8 fmol/well), precise (intra- and inter-assay CV 4-10% and 8-12%, respectively for sample concentration in the range 122-1330 pmol/L) and showed good agreement with conventional radioimmunoassays (r = 0.99).
