αTF validation data. The αTF preparation bound to murine TF peptide (extracellular domain) in solid-phase binding assay (left) and to murine fibroblasts (middle top), in which case binding was blocked by the immunogenic peptide (middle bottom). The αTF weakly inhibits TF-induced coagulation (right). BSA indicates bovine serum albumin; and OD, optical density. Original magnification, × 600.
