Description

Interleukin-6 (IL-6), also known as IFN-β2, BSF-2, and HPGF, is a multifunctional cytokine which regulates immune responses, acute-phase reactions and hematopoiesis.  Reported cellular targets for IL-6 action include hepatocytes, B and T lymphocytes, neurons, tumor cells and multipotent hematopoietic cells.  Mouse IL-6 is a 21.7 kD protein containing 187 amino acid residues.  Recombinant mouse IL-6 (Cat. No. 554582) is supplied as a frozen liquid comprised of 0.22 µm sterile-filtered aqueous buffered solution, glycerol and bovine serum albumin, with no preservatives.  Recombinant mouse IL-6 is ≥ 95% pure as determined by SDS-PAGE, and an absorbance assay based on the Beers-Lambert law.  The endotoxin level is ≤ 0.1 ng per µg of mouse IL-6, as measured in a chromogenic LAL assay.

Preparation And Storage

Store product at -80°C prior to use or for long term storage of stock solutions. Rapidly thaw and quick-spin product prior to use. Avoid multiple freeze-thaws of product. This preparation contains no preservatives, thus it should be handled under aseptic conditions.

Recommended Assay Procedures

Upon initial thawing, recombinant mouse IL-6 (Cat. No. 554582) should be aliquoted into polypropylene microtubes and frozen at -80°C for future use.  Alternatively, the product can be diluted in sterile neutral buffer containing not less than 0.5 - 10 mg/mL carrier protein, such as human or bovine serum albumin, aliquoted and stored at -80°C.  For in vitro biological assay use, carrier protein concentrations of

0.5 –  1.0 mg/mL are recommended.  For use as an ELISA standard, carrier protein concentrations of 5 - 10 mg/mL are recommended.  Failure to add carrier protein or store at indicated temperatures may result in a loss of activity.  Carrier proteins should be pre-screened for possible effects in each investigator's experimental system.  Carrier proteins may have an undesired influence on experimental results due to toxicity, high endotoxin levels or possible blocking activity.

ELISA Standard:  Recombinant mouse IL-6 (Cat. No. 554582) can be useful as a quantitative standard for measuring mouse IL-6 protein levels using sandwich ELISA with purified MP5-20F3 (Cat. No. 554400) as a capture antibody and biotinylated MP5-32C11 (Cat. No. 554402) as the detection antibody.  To obtain linear standard curves, investigators may want to consider using doubling dilutions of recombinant mouse IL-6 from 2000 - 15 pg/mL to be included in each ELISA plate.  For measuring mouse IL-6 in serum or plasma, investigators are highly encouraged to use the BD OptEIA™ Mouse IL-6 ELISA Set (Cat. No. 555240) or BD OptEIA™ Mouse IL-6 ELISA Kit (Cat. No. 550950).

Bioassay:  Investigators are advised that the Bioassay application is not routinely tested for this material and are highly encouraged to both titrate this material and include appropriate controls in relevant experiments.  An activity range of 1.3 - 6.7 x 10^7 units/mg, encompassing an

ED50= 150 - 750 pg/mL, has previously been reported using NFS-60 indicators cells for proliferation, with a unit defined as the amount of material needed to stimulate a half-maximal response at cytokine saturation.

Blocking: Recombinant mouse IL-6 (Cat. No. 554582) can be useful as a blocking control for flow cytometric analysis when used with PE-conjugated MP5-20F3 antibody (Cat. No. 554401).  Investigators are advised that the blocking application is not routinely tested for this material.  Intracellular cytokine staining techniques and the use of blocking controls are described in detail by C. Prussin and D. Metcalfe.
