Recombinant Human Interleukin-35/IL-35

Cat.No.: CM89

Recombinant human Interleukin 35
Description
Recombinant Human Interleukin-35 is produced by our Mammalian expression system and the target gene encoding Arg21-Lys229&Arg23-Ser219 is expressed with a Fc tag at the C-terminus.
Accession #:Q14213&P29459
Known as:Interleukin 35; IL35; hIL35
Formulation
Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.
Quality Control
Purity: Greater than 80% as determined by reducing SDS-PAGE.
Endotoxin: Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.
Reconstitution
Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minim
Storage
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Background
Interleukin-35 is a newest and potent suppressive cytokine of the IL-12 family. Unlike other members of the IL-12 family which are produced mainly by antigen-presenting cells (APCs), IL-35 has been identified as a potentially immunosuppressive cytokine primarily produced by regulatory T (Treg) cells, and to a lesser extent by activated dendritic cells and macrophages. IL-35 is composed of the IL-12 p35 subunit and the IL-27 Epstein–Barr virus-induced protein 3 (EBI3) subunit. IL-35 plays an important role in many disease models and has been recently shown to have additional functions aside from inhibition of proliferation, including inducing its own expression in non-Treg cells.
