Enzyme immunoassay of immunoreactive trypsin in serum and blood spots
1Department of Medical Microbiology, University of Wales College of Medicine, Cardiff, U. K.
An enzyme immunoassay method for the assay of serum immunoreactive trypsin (IRT) is described. The method is a two site binding assay carried out on microtitre plates as the solid phase. Wells were coated with affinity purified anti-human trypsin and biotinylated anti-trypsin and avidin-beta-galactosidase were used as the second antibody and detection system respectively. The assay was sensitive enough to determine IRT concentrations in either serum or dried blood spots. A good correlation was obtained when the method was compared with the Hoechst radioimmunoassay method.
