Human vWF Protein (His Tag)

分子别名（Synonym）:F8VWF,Von Willebrand Factor,VWD 种属（Species）：Human 表达系统（Expressed Host）：CHO Stable Cells 制剂（Buffer）：Lyophilized from sterile PBS, pH 7.4 分子量（Molecule Mass）：The secreted recombinant human vWF consists of 2802 amino acids after removal of the signal peptide and has a predicted molecular mass of 308 kDa. Purified rhvWf exists as both the pro form with the pro peptide (307 kDa) and the mature form (226 kDa), which migrates as doublets with apparent molecular mass of 260 and 350 kDa respectively in SDS-PAGE under reducing conditions due to glycosylation. 内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method. 生物活性(Activity)： 表达区间（Protein Construction）：A DNA sequence encoding the pro form of human von Willebrand factor (NP_000543.2) (Ser 2-Lys 2813) was expressed with a C-terminal polyhistidine tag. 存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution. 运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
