IL-35 Recombinant Protein

Interleukin-35 is a glycosylated, heterodimeric protein consisting of the p35 subunit from IL-12 (IL-12α) and the β subunit from IL-27 (EBI3) . IL-35 can be expressed by regulatory T-cells (Tregs), macrophages, and certain trophoblast and dendritic cells. It is induced in response to inflammation, and generally acts as an inflammation suppressor. IL-35 suppresses inflammation by exerting multiple activities, including the induction of regulatory T-cells and the suppression of Th17 cells. Recombinant Human IL-35 produced from HEK293 cells is a glycosylated protein, primarily heterodimeric, that migrates as a diffuse band centered at an apparent molecular weight of about 60 kDa by SDS-PAGE analysis under non-reducing conditions. Recombinant Human IL-35 expressed in HEK293 cells contains 406 amino acid residues and has a calculated molecular weight of 45.8 kDa.

The recombinant protein is stable for at least 2 years from date of receipt at -20˚ C. Reconstituted protein is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚ C. As with any protein, exposing the recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
