Claims11
A method for the assay of an immunological ligand comprising the steps of:
- a) contacting a specimen suspected on containing said immunological ligand with one or more receptors to said ligand, at least one of which is labeled for detection, to form a detectable immunological complex between said ligand and said one or more receptors,
- b) separating said detectable complex from uncomplexed materials by washing with an aqueous wash solution, which contains a complexing agent for metal ions, and
- c) detecting either the amount of detectable complex or uncomplexed labeled receptor.
