Abstract
The present invention relates to microspheres comprising protein signal precursor molecules, or a carrier protein bonded to signal precursor molecules, wherein said signal precursor molecules are activatable to generate a detectable signal while remaining bonded to the carrier protein. Also disclosed is a method of making such microspheres comprising the steps of mixing protein molecules with a matrix former in solution; adding a reducing reagent to the mixture; removing the reducing reagent; and removing the matrix former to leave microspheres of protein molecules. Also disclosed are bioassay methods using the microspheres to provide signal amplification, including an amplification cycling procedure.
