Recombinant Human IL-6 Protein-T&L

Product Information Protein sequence A DNA sequence encoding the human IL-6（NP_000591.1：V30-M212）was expressed with a His-tag at the C-terminus Expression Host HEK293 cells QC Testing Purity > 90 % as determined by SDS-PAGE Activity Determined by the dose-dependent stimulation of the proliferation of TF-1 cells. The expected ED50 for this effect is ≤ 1 ng/mL Endotoxin Level < 0.1 EU per μg of the protein as determined by the LAL method Molecular Mass The Recombinant Human IL-6 Protein predicts a molecular mass of 21.6 kD Formulation Lyophilized from sterile PBS, pH 7.4. Normally 6 % mannitol are added as protectants before lyophilization Stability & Storage 24 months at 2 °C to 8 °C in lyophilized state. 6 months at -20 °C under sterile conditions after reconstitution.12 months at -80 °C under sterile conditions after reconstitution.Recommend to aliquot the protein into smaller quantities after reconstituting with water for injection, normal saline or PBS, an
