Calibration device for heterogeneous immunoassay

摘要

A device is disclosed for use in a simultaneous calibration assay method wherein a conjugate of a catalyst and a member of a specific binding pair ("mip") is employed. The present device comprises a surface to which a receptor is non-diffusively bound. The receptor is capable of specific binding to the conjugate of the catalyst and mip and is substantially incapable of binding to the catalyst or the mip apart from the conjugate. The surface may be an integral part of, or separate from, a support.
