分子别名（Synonym）:FRP-4,FRPHE,sFRP-4

种属（Species）：Human

表达系统（Expressed Host）：CHO Stable Cells

产品状态（Buffer）：Lyophilized from sterile PBS, pH 7.4.

分子量（Molecule Mass）：The recombinant human SFRP4 consists 336 amino acids and predicts a molecular mass of 39 kDa.

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) (Ser2-VAL346) was expressed with a polyhistidine tag at the C-terminus.

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.
