7.背景Background:
Interleukin-18 (IL-18), an 18 kDa cytokine, is a single, non-glycosylated polypeptide chain containing 157 amino acids. IL-18 was previously known as interferon-gamma inducing factor (IGIF). This pleiotropic cytokine is produced by monocyte/macrophage cells. Like IL-12, IL-18 plays an important role in cell-mediated immune responses. 
8保存和稳定性Storage&Stability:
Avoid repeated freeze and thaw cycle.Store at 2-8℃ for delivery and store at -20 or -70℃ for future use. The loss rate of the target protein which describes the stability was determined by accelerated thermal degradation test.That is to incubate the protein at 37℃ for 48h and no obvious degradation and precipitation were observed.The loss of this protein is less than 5% within the expiration date under appropriate storage condition.
