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 Murine Interleukin-1 alpha (rMuIL-1α) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1 % BSA. Storage & Stability Lyophilized recombinant Murine Interleukin-1 alpha (rMuIL-1α) 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 Interleukin-1 (IL-1) is a family of related peptides that are produced by mononuclear phagocytes and other cell types that have been stimulated by microbes or various microbial products. IL-1 has been shown to initiate or augment a number of biological responses that are proinflammatory in nature. Recombinant Murine Interleukin-1 alpha is a non-glycosylated polypeptide chain containing 156 amino acids and having a molecular mass of 17.9 kDa. Treatment with recombinant murine interleukin-1 alpha (rIL-1 alpha) significantly enhances the resistance of mice to infection by the facultative intracellular pathogen Listeria monocytogenes[1]. Members of the IL-1 family such as IL-1α and IL-1β are pro-inflammatory cytokines. Increased IL-1α and IL-1β levels have been detected separately in cigarette smoke (CS)-treated animals and inhibition of the respective signaling pathways result in anti-inflammatory activity[2]. |
