Human sFRP4 Protein (His Tag)

分子别名（Synonym）:FRP-4,FRPHE,sFRP-4 种属（Species）：Human 表达系统（Expressed Host）：HEK293 Cells 制剂（Buffer）：Lyophilized from sterile PBS, pH 7.4 分子量（Molecule Mass）：The recombinant human sFRP4 consists of 336 amino acids after removal of the signal peptide and has a predicted molecular mass of 39 kDa. In SDS-PAGE under reducing conditions, it migrates with an apparent molecular mass of 55-60 kDa due to glycosylation. 内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method. 生物活性(Activity)：Measured by its ability to inhibit Wnt3a-induced alkaline phosphatase production by C3H10T 1/2 2A6 mouse embryonal fibroblast cells. 表达区间（Protein Construction）：A DNA sequence encoding the human sFRP4 (NP_003005.2) (Ser 2-Val 346) 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.
