  • Publication number: 20050170446
    Abstract: A sandwich assay method for detecting the presence of a target molecule in a sample comprising a complex biological fluid is provided. The assay comprises providing a first affinity ligand with affinity for the target molecule, which affinity ligand is capable of being immobilized to a solid support; applying the sample in such a way that binding of a target molecule, if present in the sample, to the first affinity ligand is enabled; applying a second affinity ligand with affinity for the target molecule, the application enabling binding of the second affinity ligand to the target molecule; removing second affinity ligand not bound to target molecule; and detecting the presence of the second affinity ligand, such presence being an indicator of the presence of a target molecule in the sample. The first affinity ligand is immobilized to the solid support at any stage before said detection, and at least one of the first and second affinity ligands is an affinity ligand other than an antibody.

  • Publication number: 20040077017
    Abstract: The present invention relates to methods of detecting the presence of target molecules in a sample, in particular protein target molecules. In particular, the invention provides a method of detecting the presence of a target molecule in a sample which comprises contacting said sample with a detector protein, said detector protein being a binding partner for said target molecule and being derivatized by two fluorescent reporter groups, the energy transfer between said reporter groups undergoing a detectable change on binding of the target molecule to said detector protein and a detector protein molecule having a binding site for a target molecule and having covalently attached thereto two fluorescent reporter groups, the energy transfer between said reporter groups undergoing a detectable change on binding of the target molecule to said detector protein. The detector protein comprises or consists f a combinatorial protein.
