Active Recombinant Human IL6 protein, C-His-tagged

• Cat.No.: IL6-4285H
• Product Overview: Active Recombinant Human IL6 protein(NP_000591.1)(Val30-Met212) is expressed in HEK293, fused with a 6xHis tag at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 30-212 aa
• Form: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
• Bio-activity: 1.Measured by its binding ability in a functional ELISA.Immobilized Human IL6R at 1 μg/mL (100 μL/well) can bind Human IL-6 with a linear range of 2-15 ng/mL. 2.Measured in a cell proliferation assay using TF-1 Human erythroleukemic cells. The ED50 for this effect is 0.10-0.40 ng/mL. The specific activity of Recombinant Human IL-6 is >1.2 × 10^8 IU/mg, which is calibrated against the human IL‑6 WHO International Standard (NIBSC code: 21/308).
• Molecular Mass: 21.65 kDa
• Endotoxin: < 0.1 EU/μg of the protein by LAL method.
• Purity: ≥ 95 % as determined by SDS-PAGE.
• Storage: Store at -20°C.Store the lyophilized protein at -20°C to -80°C up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20°C for 3 months, at 2-8°C for up to 1 week.
• Reconstitution: Centrifuge the tube before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
