| pubmed-article:6337177 | pubmed:abstractText | The proportion of immunoreactive somatomedin-C (IR-Sm-C) in blood that is available for measurement in the RIA is influenced by whether the sample is processed as serum or plasma, by how promptly the sample is chilled and frozen, by whether the reaction is carried out in glass or polystyrene tubes and by whether the incubation mixture contains protamine or heparin. Although protamine buffers and polystyrene tubes increase the availability of purified somatomedin-C (Sm-C), they decrease the detectability of Sm-C in serum. By incubating serum at neutral or acid pH, this IR-Sm-C can be made available for measurement, suggesting that incubation alters the nature of the linkage between Sm-C and its binding proteins or causes a conformational change in the binding protein, resulting in greater exposure of IR-Sm-C. The increment in measurable IR-Sm-C that occurs at neutral pH appears to be due to the action of proteolytic enzymes since it is time, temperature, and pH dependent and is inhibited by a variety of protease inhibitors and chelating agents. The increment which occurs at acid pH is not inhibited by chelating agents or elevated temperature and must be due in part to acid hydrolysis of Sm-C and its binding proteins. However, since the acid-induced increment is optimal within a narrow pH range and falls off sharply below pH 3.5, acid proteases may also be involved. These observations, which provide insight into the nature of the serum proteins with which Sm-C is associated, bear on the interpretation of results of serum somatomedin measurements carried out with different methods. They also may aid in delineating the mechanisms by which the somatomedin contained in the macromolecular complex in serum is made available to tissues. | lld:pubmed |
