Background | Interleukin 18 (IL-18), also known as interferon-gamma-inducing factor (IGIF) and IL-1γ, is a cytokine which shares biologic activities with IL-12 and structural similarities with the IL-1 family of proteins. IL-18 was originally cloned from liver cells and has since been shown to be expressed by monocyte/macrophages, osteoblasts and keratinocytes. Caspase-1 (IL-1 beta-converting enzyme) has been implicated in the physiological processing of pro-IL-18 to IL-18. Similarly to IL-12, human IL-18 has been shown to enhance NK cell activity in PBMC cultures. Human IL-18 has also been found to induce the production IFN-γ and GM-CSF while inhibiting the production of IL-10 by PBMC. On enriched human T cells, human IL-18 can enhance Th1 cytokine production and stimulate cell proliferation via an IL-2-dependent pathway. In the mouse system, IL-18 has been shown to be a costimulatory factor for the activation of Th1, but not Th2, cells. IL-18 was found to selectively enhance the FasL-mediated cytotoxicity of Th1, but not Th0 or Th2, cells. IL-18 has also been shown to induce activated B cells to produce IFN-γ that inhibits IgE production. |

保存條件:
IL18 Rabbit Polyclonal Antibody (KO Validated) -20ºC保存,Western一抗稀釋液-20ºC或4ºC保存,一年有效。Western一抗稀釋液優先推薦4ºC保存,長期不使用可以考慮-20ºC保存,但凍融可能會導致出現輕微的渾濁和少量不溶物。
注意事項:
如果本抗體用于Western blot (WB)、免疫熒光(IF)、免疫細胞化學(ICC)等實驗,請注意回收使用過的稀釋抗體。回收的抗體通常至少可以重復使用5-10次。稀釋后的抗體,包括已經使用過的稀釋抗體,請4℃保存。
回收后重復使用的抗體,使用方法同新鮮稀釋的抗體。如果在重復使用過程中發現抗體出現輕微混濁現象,可以10,000g離心1-3分鐘,取上清用于后續檢測。如果回收的抗體出現明顯的絮狀物或長霉長菌等情況,則可以考慮廢棄該抗體。
提供的Western一抗稀釋液也可以用于免疫熒光(IF)、免疫組化(IHC)、免疫細胞化學(ICC)等適當用途。如果希望獲得最佳的檢測效果,請考慮使用上述檢測專用的一抗稀釋液。
