The Human Cytokeratin Fragment 19 CLIA Kit is designed, developed, and produced for the quantitative measurement of human CYFRA21-1 level in serum samples. The assay utilizes a two-site “sandwich” technique with two antibodies that bind to different epitopes of CYFRA21-1.
Assay calibrators, controls, or serum samples are added directly to a reaction vessel together with magnetic particles antibody. The magnetic particles capture the CYFRA21-1 in the form of “magnetic particles–CYFRA21-1 antibody–CYFRA21-1–acridinium ester CYFRA21-1 antibody”.
Materials bound to the solid beads are held in a magnetic field while unbound materials are washed away. Then trigger solutions are added to the reaction vessel, and light emission is measured with the ECL100 Chemiluminescent Immunoassay Analyzer. The relative light units (RLU) are proportional to the concentration of CYFRA21-1 in the sample. The amount of analyte in the sample is determined from a stored, multi-point calibration curve and reported in serum CYFRA21-1 concentration.
