No. 10,232,022, which is a continuation of U.S. patent application Ser. No. 12/603,064, filed Oct. 21, 2009, now abandoned, which claims priority to U.S. Provisional Application No. 61/107,273, filed Oct. 21, 2008, and this application is also a continuation of U.S. patent application Ser. No. 14/693,078, filed Apr. 22, 2015, which is a continuation of U.S. patent application Ser. No. 12/342,646, filed Dec. 23, 2008, now abandoned, which claims priority to U.S. Provisional Application No. 61/017,881, filed Dec. 31, 2007, and which claims priority to U.S. Provisional Application No. 61/017,418 filed Dec. 28, 2007.\n\nGenerally, the invention relates to formulations of lyophilized recombinant VWF and methods for making a lyophilized composition comprising recombinant VWF.\n\nVon Willebrand factor (VWF) is a glycoprotein circulating in plasma as a series of multimers ranging in size from about 500 to 20,000 kD. Multimeric forms of VWF are composed of 250 kD polypeptide subunits linked together by disulfide bonds. VWF mediates initial platelet adhesion to the sub-endothelium of the damaged vessel wall. Only the larger multimers exhibit hemostatic activity. It is assumed that endothelial cells secrete large polymeric forms of VWF and those forms of VWF which have a low molecular weight (low molecular weight VWF) arise from proteolytic cleavage. The multimers having large molecular masses are stored in the Weibel-Pallade bodies of endothelial cells and liberated upon stimulation.",
