| |
| Source: | Produced in E. coli. Non-glycosylated protein, containing 187 amino acids. |
| |
| UniProt ID: | P08505 |
| |
| Formulation: | Lyophilized. Sterile filtered. |
| |
| Purity: | ≥95% (HPLC, Reducing and Non-reducing SDS-PAGE, UV spectroscopy at 280 nm) |
| |
| Endotoxin Content: | ≤1 EU/μg protein measured by kinetic LAL analysis. |
| |
| Appearance: | White lyophilized (freeze-dried) powder. |
| |
| Biological Activity: | The activity is determined by dose-dependent induction of 7TD1 cell proliferation which is typically observed at concentations <0.02ng/ml. |
| |
| Reconstitution: | When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized mouse IL-6 in 10 mM HCl to 0.1-1.0 mg/ml, which can be further diluted to other aqueous solutions. |

| Use/Stability: | It is recommended that a carrier protein (0.1% HSA or BSA) is added for long term storage. |
| |
| Handling: | Centrifuge the vial before opening the cap. After reconstitution, prepare aliquots and store at -20°C. |
| |
| Scientific Background: | Interleukin 6 (IL-6) is an important pro-inflammatory and anti-inflammatory cytokine expressed by T cells, macrophages and muscle cells. IL-6 signals through a receptor complex containing two receptors, IL-6Rα and gp130. IL-6 has an important function in promoting fever and can serve to stimulate an immune response to trauma. IL-6 is often used for growth of hybridoma cell lines. Human IL-6 is active on mouse and rat cells. |
