| Short Description : | Recombinant-Human Periostin/PN/POSTN-C-6His protein was developed in hek293 cells using the region Asn22-Gln836. For use in research applications. |
| Host: | HEK293 cells |
| Note: | STRICTLY FOR FURTHER SCIENTIFIC RESEARCH USE ONLY (RUO). MUST NOT TO BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS. |
| Conjugation: | Unconjugated |
| Formulation: | Lyophilised from a 0.22 Mu m filtered solution of PBS, pH 7.4. |
| Storage Instruction: | Store at-20°C for up to 1 year from the date of receipt, and avoid repeat freeze-thaw cycles. |
| Immunoreactivity: | Measured by its ability to induce adhesion of ATDC5 mouse chondrogenic cells. Immobilized Recombinant Human Periostin/OSF‑2 at 10 µg/mL (100 µL/well) induces >19% cell adhesion. |

| 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. |
