Vitronectin (serum spreading factor), a cell-adhesive glycoprotein present in mammalian serum, has previously been the subject of conflicting reports concerning its binding to heparin. Vitronectin purified from human plasma does not bind to heparin under physiological conditions, but it does so after treatment with denaturing agents including 8M urea or 6M guanidine-HCl, or heating at 100°C for 5min. These treatments seem to expose a heparin-binding site in vitronectin; this finding thus resolves the conflicts concerning this function.
