ABSTRACT:
The invention provides a method for extending the plasma half-life of heparin-binding proteins by coadministering such proteins with a therapeutically acceptable compound capable of inhibiting their binding to a low affinity heparin-like binding site on the surface of cells. In one embodiment of the invention, the heparin-binding protein is a growth factor or selectin. The binding inhibitory compound can, for example, be a purified native heparin preparation, a heparin fragment, or another polyanionic compound, such as dextran sulfate, heparan sulfate, pentosan sulfate, or hyaluronate.
