the purified glycoprotein was used to develop a rapid specific radioimmunoassay for its measurement in human serum or plasma by the use of the tamm-horsfall glycoprotein , labelled with ( 125 ) i by the chloramine-t method as the tracer , an antiserum raised in rabbits , and separation of the bound and free fractions by a second antibody covalently linked to magnetizable particles .
