Abstract
The invention provides high and low molecular weight fraction of von Willebrand Factor (vWF), which can be obtained by absorbing vWF to a heparin affinity support followed by eluting the vWF at differing salt concentrations The low molecular weight fraction is predominantly dimers and tetramers, and the high molecular weight fraction is predominantly larger multimers.
