Abstract
A method for capturing PSA and its molecular forms that may be in a fluid biological material including the steps of: preparing a bed of magnetic beads by binding thiophilic ligands to the beds where the thiophilic ligands bind PSA and its complexes, said thiophilic ligands comprising a two part structure wherein one part can be characterized as a hy6drophilic electron acceptor and the other part is sulfur which acts as an electron donor; selecting a sample of a fluid biological material to be tested for PSA and its complexes; introducing the sample into the magnetic beads bound to thiophilic ligands so that PSA and its complexes bind to the thiophilic ligand; and magnetically removing the beads from unbound portions of the sample.
