Category
| Source | Human IL-6, amino acids Pro29-Met212 (Accession # NM_000600) was expressed in E. coli. |
|---|---|
| Molecular Mass | The 185 amino acid N-terminal methionylated recombinant protein has a predicted molecular mass of 21 kD. The DTT-reduced and non-reduced protein migrate at approximately 23 kD by SDS-PAGE. |
| N-terminalSequence Analysis | Pro-Val-Pro-Pro-Gly-Glu-Asp-Ser-Lys-Asp |
| Purity | ≥ 95%, as determined by Coomassie stained SDS-PAGE |
| Formulation | 0.1 µm filtered protein solution is in 10 mM NaH2PO4, 150 mM NaCl, pH 7.2. |
| Endotoxin Level | Less than or equal to 0.1 EU per µg protein as determined by the LAL method |
| Residual Host Cell Protein Content | ≤ 0.500 ng/µg by ELISA |
| Concentration | 500 µg/mL |
| Storage & Handling | Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% endotoxin-free BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week or stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles. |
