| Size | 20 µg/100 µg/1 mg |
| Species | Human |
| Synonyms | CRISTIN3 Protein, FLJ40906 Protein, RSPO Protein, RSPONDIN Protein |
| Purity | Purity is ≥95% as determined by SDS-PAGE and SEC-HPLC, and ≥95% by SEC-MALS (routinely tested). |
| Formulation | The product is lyophilized from a sterile PBS, pH 7.4. Cryoprotectants, specifically 5 %-8 % trehalose, mannitol and 0.01% Tween80, are added prior to the lyophilization process. |
| Endotoxin | <1.0 EU per μg protein. |
| Expressed Host | HEK293 Cells |
| Protein Construction | The coding sequence for the human RSPO1 (Met 1-Ala 263) was expressed fused with a polyhistidine tag at the C-terminus. |
| N Terminal | Ser 21 |
| Molecule Mass | 28.2 kDa |
| Storage | The product can be stored for twelve months from its arrival date when kept at temperatures between -20°C and -80°C. |
| Shipping Information | Typically, recombinant proteins in their lyophilized form are transported under ambient conditions. For bulk packages, the product is supplied as a frozen liquid and, unless specified otherwise by the customer, is shipped with blue ice. |
| Notes | To maintain protein integrity, it is best to store it in separate aliquots. Furthermore, avoid subjecting the sample to repeated freezing and thawing. |
