The Fecal C. Difficile Toxin A + B CLIA Kit is designed, developed, and produced for the quantitative measurement of C. Difficile Toxin A & B antigen in fecal samples. The assay utilizes a two-site “sandwich” technique with two antibodies that bind to different epitopes of Toxin A & B antigen.
Assay calibrators, controls, or extracted fecal samples are added directly to a reaction vessel. Simultaneously, a biotinylated antibody, a streptavidin-coated magnetic particle, and subsequently an acridinium ester-conjugated antibody are added to the vessel. The magnetic particles capture the biotin antibody as well as an immuno complex in the form of “magnetic particles – biotinylated anti-Toxin A & B antibody –Toxin A & B antigen– acridinium ester conjugated anti-Toxin A & B antigen antibody”.
The materials bound to the solid phase are held in a magnetic field while unbound materials are washed away. Then, the trigger solution is added to the reaction vessel, and the light generated by the reaction is measured with the ECL100 Chemiluminescent Immunoassay Analyzer. The relative light units (RLU) are proportional to the concentration of Toxin A & B antigen in the sample. The amount of analyte in the sample is determined from a stored, multi-point calibration curve and reported in fecal C. Difficile Toxin A & B antigen concentration.
