Reconstitution Reconstitute the lyophilized recombinant Human Interleukin-17 (rHuIL-17) to 100 µg/mL using ddH2O. Storage & Stability Lyophilized recombinant Human Interleukin-17 (rHuIL-17) 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 The interleukin-17 (IL-17) cytokines, IL-17A to IL-17F, are emerging as critical players in host defence responses and inflammatory diseases. The interleukin-17 (IL-17) cytokines are emerging as key players in immune responses. The first member to be identified, IL-17A, is originally cloned as cytotoxic T-lymphocyte antigen-8, a gene sharing homology with the HSV13 gene from herpesvirus Saimiri. The other members, IL-17B to IL-17F are subsequently identified based on their homology to IL-17A. These proteins are highly conserved at the C terminus, and contain five spatially conserved cysteine residues that mediate dimerization. Members of the IL-17 receptor family, IL-17RA to IL-17RE, mediate the biological functions of these cytokines. Accumulating evidence indicates that these interactions induce pro-inflammatory programmes[1]. |
