Phosphorothioate oligodeoxynucleotides bind to basic fibroblast growth factor, inhibit its binding to cell surface receptors, and remove it from low affinity binding sites on extracellular matrix.

We studied the interactions of phosphorothioate oligodeoxynucleotides and heparin-binding growth factors. By means of a gel mobility shift assay, we demonstrated that phosphodiester and phosphorothioate homopolymers bound to basic fibroblast growth factor (bFGF). Binding of a probe phosphodiester ol...
