Protein Construction
A DNA sequence encoding the p35 subunit of human IL12, termed as IL12A (NP_000873.2) (Met1-Ser219) was fused with the C-terminal His-tagged Fc region of human IgG1 at the C-terminus, constructed the plasmid 1; A DNA sequence encoding the human IL27B, (NP_005746.2) (Met1-Lys229) was fused with the C-terminal flag-tagged Fc region of human IgG1 at the C-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the heterodimer was purified.

Molecule Mass
The recombinant human IL12A&IL27B comprises 905 (447+458) amino acids and has a calculated molecular mass of 102 (50.7+ 51.3) KDa. The apparent molecular mass of the recombinant human IL12A&IL27B is approximately 60 & 63 KDa respectively in SDS-PAGE under reducing conditions.
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 hard copy of CoA.
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.

IL-35 Background Information

IL12A is a subunit of a cytokine that acts on T and natural killer cells, and has a broad array of biological activities. 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.
