by use of a highly specific radioimmunoassay for somatomedin-c and less specific radioreceptor assays for insulin-like activity and somatomedin-c , evidence has been obtained for the existence of two major classes of somatomedins : neutral somatomedin , which is more insulin-like , and basic somatomedin , which is more rigorously growth hormone dependent , and which , in some systems , is s more powerful stimulant of growth .
