Abstract (en)

[origin: WO9502824A1] Method for the quantitative determination of human thyroid peroxidase (hTPO) in biological fluids, culture media, tissue extracts and fluids containing highly purified natural hTPO or recombinant hTPO, in which the determination is carried out as a sandwich assay known per se, using a first monoclonal antibody against hTPO and at least one further monoclonal antibody against hTPO (MAB1, MAB2), of which the former (MAB1) recognises hTPO in a region which is sensitive to denaturing and is involved in the binding of the autoantibodies against hTPO and in enzyme inhibition, while the one or more further antibodies (MAB2) recognises hTPO in a region whose binding properties are not essentially impaired by denaturing of hTPO.
