分子别名(Synonym):CRISTIN3,R-Spondin 1,RSPO
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 RSPO1 consists of 243 amino acids and has a predicted molecular mass of 26.8 kDa. As a result of glycosylation, the apparent molecular mass of it is approximately 40 and 31 kDa in SDS-PAGE under reducing conditions.
内毒素(Endotoxin):<1.0 EU per μg by the LAL method.
生物活性(Activity):Measured by its ability to induce activation of ßcatenin response in a Topflash Luciferase assay using HEK293T human embryonic kidney cells. The ED50 for this effect is typically 0.1-0.9 μg/mL in the presence of 5 ng/mL recombinant mouse Wnt3a.
表达区间(Protein Construction):A DNA sequence encoding the human RSPO1 (NP_001033722.1) ( Ser 2-Ala 263 )was expressed and purified.
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.
Store it under sterile conditions at -20℃ to -80℃ upon receiving. Recommend to aliquot the protein into smaller quanti ࿒ ࿒ 5516} ā
