Ghrelin dose-dependently displaces 125I-ghrelin from borosilicate glass. To determine whether binding of 125I-ghrelin to borosilicate could be prevented by addition of another chemical, different concentrations of ghrelin (A), GLP-1 (B), Fmoc-arginine (C) and BSA (D) were added to the test tubes together with ghrelin radiolabel and incubated. While cold ghrelin and BSA dose-dependently displaced 125I-ghrelin from the borosilicate glass surface, GLP-1 and Fmoc-arginine did not.
