Purity | > 97 % as determined by SDS-PAGE |
Protein Construction | A DNA sequence encoding the soluble form of mouse IL21 (Q9ES17) (Pro 25-Ser 146) was expressed, with an initial Met at the C-terminus. |
Bio-activity | Measured by its ability to induce Interferon gamma secretion by human natural killer lymphoma NK-92 cells. The ED50 for this effect is typically 4-20 ng/ml. |
Research Area | Immunology |Inflammation / Inflammatory Mediator |Inflammatory Cytokines & Chemoki and Receptors |Common gamma Chain Receptor Family |
Formulation | Lyophilized from sterile PBS, pH 7.5 1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. |
