ghbp activity was measured by incubating 125i-hgh ( human growth hormone ) ( approximately 25,000 c.p.m . ) with serum ( 100 microliters ) in the presence and in the absence of excess unlabelled hgh , followed by separation of specifically bound 125i-hghbp complexes from free 125i-hgh by gel filtration on ultrogel aca44 minicolumns .
