Name :
Recombinant Human IL-35 Protein (Fc-Flag & Fc-His Tag)

Biological Activity :

Background :
IL12A is a subunit of a cytokine that acts on T and natural killer cells and has a broad array of biological activities. The cytokine is a disulfide-linked heterodimer composed of the 35-kD subunit encoded by this gene, and a 40-kD subunit that is a member of the cytokine receptor family. IL12A, together with IL27B, form a disulfide-linked heterodimer: IL12A&IL27B. IL12A&IL27B is required for the T-cell-independent induction of IFN-gamma and is important for the differentiation of both Th1 and Th2 cells. The responses of lymphocytes to this cytokine are mediated by the activator of transcription protein STAT4. Nitric oxide synthase 2A (NOS2A/NOS2) is found to be required for the signaling process of IL12A&IL27B in innate immunity.

Protein Construction :
A DNA sequence encoding the p35 subunit of human IL12, termed as IL12A (P29459-1) (Met1-Ser219) was fused with a C-terminal Fc region of human IgG1 tag followed by a FLAG tag, constructed the plasmid 1; A DNA sequence encoding the human IL27B (NP_005746.2) (Met1-Lys229) was fused with a C-terminal Fc region of human IgG1 tag followed by a polyhistidine tag, constructed the plasmid 2. The two plasmids were co-expressed and the heterodimer was purified.

Buffer Solution :
Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hardcopy of datasheet.

Shipping :
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

Redissolution :
A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
