Predicted MW 75 kDa
Purity >98% by SDS-PAGE and HPLC
Buffer Presentation State: Purified
State: Lyophilized purified protein
Stabilizer: None
Bioactivity Biological:
The ED50 was determined by the induction of IFN-γ from NK cells co-stimulated with IL-18 is ≤ 1.0 ng/ml, corresponding to a specific activity of ≥ 1 x 106 units/mg.
Endotoxin < 0.1 ng per µg of IL-12
Reconstitution Restore in 1x PBS, pH 7.2-7.4 to a concentration of 0.2 mg/ml. This solution can then be diluted into other aqueous buffers and stored at 4°C for 1 week or –20°C for future use.
Preparation Lyophilized purified protein
Protein Description Recombinant Human IL-12 is a 75.0 kDa heterodimeric glycoprotein consisting of disulfide-linked 35 kDa (p35) and 40 kDa (p40) subunits (503 total amino acid residues).
Storage Store lyophilized at 2-8°C for 6 months or at -20°C long term.
After reconstitution store the antibody undiluted at 2-8°C for one month 
or (in aliquots) at -20°C long term.
Avoid repeated freezing and thawing.
Stability Shelf life: one year from despatch.

Summary This gene encodes 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. This cytokine is required for the T-cell-independent induction of interferon (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 this cytokine in innate immunity. [provided by RefSeq, Jul 2008]
