Abstract

A conjugate of at least two binding sites that bind specifically to the analyte-specific binding region of the receptor that is used for detection in a test, wherein the binding sites are linked by at least one soluble carrier substance and the conjugate is a product of a synthetic or recombinant production, dissolved in an aqueous solution in an exactly known amount is particularly suitable as a stable calibrator in a test for the detection of an analyte.
