Storage & Solubility Information
| Bioactivity | Immobilized Human Periostin, His Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Anti-Periostin Antibody, hFc Tag with the EC50 of 18.5ng/ml determined by ELISA. |
| Description | Periostin/OSF-2 Protein, Human, Recombinant (aa 22-836, His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 92.1 kDa and the accession number is Q15063. |
| Species | Human |
| Expression System | HEK293 Cells |
| Tag | C-His |
| Accession Number | Q15063 |
| Construction | Asn22-Gln836 |
| Protein Purity | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization. |
| Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
| Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Synonyms | TRIF52, POSTN, PNRP11-412K4.1, PN, Periostin, PDLPOSTN, OSF-2, OSF2, Fasciclin I-like |
| Research Background |
| Molecular Weight | 92.1 kDa (predicted). Due to glycosylation, the protein migrates to 93-100 kDa based on Tris-Bis PAGE result. |
| Storage | Store at low temperature Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months |
