Fecal Human Pancreatic Elastase 1 CLIA Kit

Background

The EDI™ Fecal Pancreatic Elastase 1 CLIA Kit is designed, developed, and produced for the quantitative measurement of pancreatic elastase-1antigeninfecalsamples. The assay utilizes a two-site “sandwich” technique with two antibodies that bind to different epitopes of PE-1antigen. Assay calibrators, controls, or extracted patient fecal samples are added directly to a reaction vessel. Simultaneously, a biotinylated antibody, a streptavidin coated magnetic particle andsubsequentlyacridinium ester conjugated antibodyare added to the reaction vessel. The magnetic particles capture the biotin antibody as well as an immuno complex in the form of “magnetic particles – biotinylatedanti-PE-1 antibody–PE-1 antigen–acridinium ester conjugated anti-PE-1 antigen antibody”. Materials bound to the solid phase are held in a magnetic field while unbound materials are washed away. Then, trigger solutions are added to the reaction vessel and light generated by the reaction is measured with the ECL100 or ECL-25 analyzer. The relative light units (RLU) are proportional to the concentration of PE-1 antigen in the sample. The amount of analyte in the sample is determined from a stored, multi-point calibration curve and reported in fecal PE-1 antigen concentration.
