Measured by the ability of the immobilized protein to enhance the adhesion of Saos-2 human osteosarcoma cells to human Fibronectin. The ED50 for this effect is 1.533 µg/mL in the presence of 0.5 µg/mL Fibronectin, corresponding to a specific activity is 652.316 units/mg.
Molecular Weight:
Approximately 43-75 kDa, based on SDS-PAGE under reducing conditions, due to the glycosylation.
