Fraction (F) II and FIII obtained by heparin-Sepharose after digestion of partially purified fibronectin (FN) with cathepsin D and F3, obtained like FIII but from untreated FN, exerted activity (arFN) on unfolded purified von Willebrand factor (vWF) that controls vWF multimer size. Our aim was to evaluate the arFN of F from commercial FN, commercial 30 kDa (with heparin affinity), 45 kDa (gelatin affinity) and 70 kDa FN fragments (gelatin and heparin affinity) and whole FN. The arFN was detected in FII, FIII, F2, F3, 30 kDa, 45 kDa and 70 kDa fragments. The least contaminated sample was the 30 kDa commercial fragment. Characterization studies of this sample revealed two bands: a blurred band of approximately 60 kDa and a sharp major band of 32 +/- 6 kDa. The 32 +/- 6 kDa band fragment failed to produce arFN because it was stronger than in F2 and FIII band fragments at the same position and with the same arFN. Our data suggest that a fragment of approximately 60 kDa that co-purified with FN, with affinity to heparin and gelatin, has the arFN that controls vWF multimer size.
