| Host: | Mammalian Cells |
| Applications: | ELISA/WB |
| Note: | STRICTLY FOR FURTHER SCIENTIFIC RESEARCH USE ONLY (RUO). MUST NOT BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS. |
| Short Description : | Recombinant-Active-Human POSTN/OSF-2-C-His protein was developed from mammalian cells and has a target region of C-His. For use in research applications. |
| Conjugation: | Unconjugated |
| Formulation: | Lyophilized from a solution in PBS pH 7.4, 5% Trehalose, 5% Mannitol. |
| Dilution Range: | Reconstitute in sterile water for a stock solution. |
| Storage Instruction: | Use a manual defrost freezer and avoid repeated freeze thaw cycles. Store at 2 to 8°C for one week. Store at-20 to-80°C for twelve months from the date of receipt. |
| Endotoxin: | <0.1 EU/Mu g of the protein by the LAL method. |
| Immunoreactivity: | Measured by its ability to induce adhesion of mouse chondrogenic cells (ATDC5). Immobilised recombinant human POSTN/OSF-2 at 10 µg/mL (100 µL/well) induces >50% cell adhesion. |
| Gene Symbol: | POSTN |
| Gene ID: | 10631 |
| Uniprot ID: | POSTN_HUMAN |
| Immunogen Region: | Asn22-Gln836 |
| Immunogen: | Homo sapiens (Human) |
| Post Translational Modifications | Gamma-carboxylation is controversial. Gamma-carboxyglutamated.gamma-carboxyglutamate residues are formed by vitamin K dependent carboxylation.this may be required for calcium binding. According to a more recent report, does not contain vitamin K-dependent gamma-carboxyglutamate residues. |
| Function | Induces cell attachment and spreading and plays a role in cell adhesion. Enhances incorporation of BMP1 in the fibronectin matrix of connective tissues, and subsequent proteolytic activation of lysyl oxidase LOX. |
