  • Formulation Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.
  • Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg mL. Stock solutions should be apportio
  • Storage This lyophilized preparation is stable at 2-8 ˚C, but should be kept at -20 ˚C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 ˚C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 ˚C to -70 ˚C. Avoid repeated freeze thaw cycles.

Background
Human IL-21 is encoded by IL-21 gene located on Chr. 4. It is a pleiotropic cytokine produced by CD4+ T cells in response to antigenic stimulation and can regulating immune system cells, for instance cytotoxin T cells and natural killer cells. Additionally, it can induce target cells division or proliferation. IL-21 elicits its effect through binding to IL-21R, which also contains the gamma chain found in other cytokine receptors such as IL-2, IL-4, IL-7, IL-9 and IL-15. IL-21 IL-21R interaction triggers a cascade of events which includes activation of the tyrosine kinases JAK1 and JAK3, followed by activation of the transcription factors STAT1 and STAT3. IL-21 shows having much relation with clinical illnesses, including cancer immunotherapy, viral infections and allergies.
