Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS, pH 7.4. Endotoxin Level <1 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human Interleukin-11 (rHuIL-11) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1 % BSA. Storage & Stability Lyophilized recombinant Human Interleukin-11 (rHuIL-11) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background Recombinant Human Interleukin-11 (IL-11) plays a very crucial role in inflammation. Being an essential cytokine, IL-11 promotes chronic gastric inflammation and also associated with STAT3 and STAT1 mediated tumorigenesis. In addition, IL-11 is also an indispensable factor in IL-13- induced Th2-mediated inflammatory disorders and tissue remodeling. IL-11 has diverse biological functions. It has a protective role against neutron radiation injury, capable of promoting a faster recovery of small intestine injuries and also functions in response to inflammation in animal models of infection. Studies have revealed that IL-11 protects animal models of sepsis from liver injuries. Although its role in platelet production in neonates remains unclear, IL-11 is reported to be involved in the endogenous cytokine response to sepsis or Necrotizing Enterocolitis (NEC) in premmies. IL-11 is also involved in NF-κB signaling pathway and inhibition of IL-6 can reduce colitis associated tumorigenesis [1]. |
