Anti-(Arg-Gly-Asp-Ser) antibody and its interaction with fibronectin, fibrinogen and platelets.


An antibody population recognizing the sequence Arg-Gly-Asp-Ser (RGDS) in fibronectin, anti-(RGDS)N, was isolated by immunoadsorption. Between 2.5% and 4.9% of antibodies were obtained from two different anti-fibronectin sera indicating that this region represents an antigenic epitope in native fibronectin.
