Lyophilized recombinant mouse Interleukin-19 (rmIL-19) remains stable up to 6 months at -80 °C from date of receipt. Upon reconstitution, rmIL-19 remains stable up to 2 weeks at 4 °C or up to 3 months at -20 °C.
Interleukin-19 (IL-19) is a cytokine belonging to the interleukin family. Structurally, IL-19 is grouped into the IL-10 sub-family, which also includes IL-20, IL-22, IL-24, and IL-26. In contrast to IL-10, which exists as a homodimer, IL-19 is stable and active as a monomer in vivo. IL-19 functions through the receptor complex composed of IL-20 Receptor alpha and IL-20 Receptor beta, which is also utilized by IL-20 and IL-24. IL-19 is produced by active monocytes and stimulated synergistically by IL-17 and IL-13. The functions of IL-19 are to promote the development and function of Th2 cells and to enhance the production of Th2 cytokines. IL-19 is implicated in aging, vascular disease, Type I diabetes, and rheumatoid arthritis. Recombinant mouse Interleukin-19 (rmIL-19) produced in E. coli is a single non-glycosylated polypeptide chain containing of153 amino acids. A fully biologically active molecule, rmIL-19 has a molecular mass of 17.7 kDa analyzed by non-reducing SDS-PAGE.
