Abstract
Surfactants bound to a ligand and dissolved in a single phase aqueous solution form a precipitate when a multivalent antiligand is added to the solution. This invention can be used in an affinity precipitation test procedure (and kit) for detecting the presence or absence of a multivalent antiligand in a sample suspected of containing the multivalent antiligand, in an affinity precipitation inhibition test procedure (and kit) for detecting the presence or absence of a target ligand in a sample suspected of containing the target ligand, and in a process for separating a multivalent antiligand from a crude material containing the multivalent antiligand.
