Human von Willebrand Factor

vWF is prepared from citrated human plasma using a combination of chromotographic procedures. Although the starting material was tested prior to initiation of the manufacturing process, and was found negative or nonreactive for anti-HIV-1/2, HIV-1 antigens, HBsAg, STS, anti-HCV, anti-HBcore and anti-HTLV I II, extreme caution should be used when handling this material as there is a margin of error in all tests. This preparation is >95percent pure as judged by SDS-PAGE under reducing conditions, and consists of large multimers as determined by electrophoresis in SDS/agarose gels. Molecular weight under native conditions ranges from 520 kDa dimer to >10,000 kDa multimers. Protein concentration determined by total protein assay. Required thawing procedure: Thaw in a 37 degree celsius water bath for 2-3 minuteswithout agitation.
