| Full Name | | Interleukin-6 (IL-6), human |
|
| Abbreviated Name-1 | rHuIL-6; rHuIL6 |
|---|
| Abbreviated Name-2 | Interleukin-6; Interleukin6 |

| Description | Interleukin-6 is a multifunctional protein originally discovered in the media of cells stimulated with double stranded RNA. IL-6 induces multiple effects, as indicated by its numerous synonyms: plasmacytoma growth factor, interferon-β-2, monocyte derived human B cell growth factor, B cell stimulating factor, hepatocyte stimulating factor, Interleukin Hybridoma/Plasmacytoma-1. GenScript Interleukin (IL)-6, human produced in E. coli is a single, non-glycosylated polypeptide chain containing 184 amino acids and having a molecular mass of 21,000 Da. The rHuIL-6 is purified by proprietary chromatographic techniques. |

| Source | E. coli |
|---|
| M.W. | 21,000 Da |
|---|
| Purity | Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC
(b) Anion-exchange FPLC
(c) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel |
|---|
| Endotoxin Level | Less than 0.1 ng/μg (IEU/μg) of rHuIL-6 |
|---|
| Specific Activity | The ED50 as determined by the dose-dependant stimulation of murine 7TD1 cells is < 0.1 ng/ml, corresponding to a Specific Activity of 5×107 IU/mg. |
|---|
| Storage | Lyophilized rHuIL-6 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution rHuIL-6 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. |
|---|
| Formulation | Each μg of rHuIL-6 contains 43 μg sodium chloride and 50 μg HSA |
|---|
| Reconstitution | It is recommended to reconstitute the lyophilized rHuIL-6 in sterile 18 MΩ-cm H2O not less than 100 μg/ml, which can then be further diluted to other aqueous solutions. |
|---|
| Quantitation | Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 0.47 as the extinction coefficient for a 0.1% (1 mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a standard solution of IL-6 as a Reference Standard. |
